Here are the different ways to deal with a toxic sibling that I’ve found helpful:

1. Recognize His Toxic Behavior First and Foremost

It took me a while to recognize my sibling’s toxic behavior because, well, sibling rivalry can be pretty normal, right?

But after years of feeling constantly belittled, having my achievements downplayed, and facing manipulative tactics, it hit me like a ton of bricks.

This wasn’t just harmless teasing anymore. And recognizing the difference was crucial.

Instead of accepting the negativity as “sibling stuff,” start paying attention to the patterns — the constant put-downs, the attempts to control, the emotional manipulation.

Once you see it for what it is, you could begin to move forward in a healthier way.

2. Tell Him You’re Not Taking Any of His BS Anymore

Taking a stand against your toxic sibling’s behavior can be scary, but it’s incredibly empowering.

I remember a time my brother made a snide comment about my promotion after I’d worked my tail off for months. I used to bite my tongue, but this time, I stopped him mid-sentence.

Using assertive communication, I calmly said,

“Look, I know we’ve had our differences, but I won’t tolerate your negativity anymore. If you can’t be happy for me, at least have the decency to keep your comments to yourself.”

It wasn’t a screaming match, nor did I stoop to his level of rudeness.

But when you stand your ground, you let your sibling know you won’t be a doormat for his negativity any longer.

3. Always Stay Calm and Maintain Respectful Communication

It can be tempting to fire back with the same energy when dealing with a toxic brother’s provocations.

Trust me, I’ve been there. But I’ve learned that staying calm is better than anyone winning an argument.

Responding with anger or defensiveness only fuels the flames. Instead, take a deep breath and don’t engage in their negativity.

This isn’t giving in. It’s protecting yourself. If your sibling becomes excessively hostile, politely excuse yourself and leave the room.


Protect your peace of mind, and don’t let him drag you down to his level. You can’t control his behavior, but you can control how you react to it.

4. Set Clear Boundaries and Limit Your Interactions Whenever Possible

It wasn’t easy, but I had to set boundaries to protect myself. This looked different depending on the situation.

Sometimes, it meant politely declining invitations to events I knew would involve drama. At other times, I limited our conversations to specific topics or set time limits for interactions.

You see, a toxic sibling may not always respect your boundaries, and that’s okay. It’s about what you can control.

It’s up to you to protect yourself from his manipulative tactics and further sibling abuse.

If limiting your interactions is necessary for your peace of mind, then that’s what you should do.

5. Prioritize Your Emotional Health, Always!

Dealing with toxic people who constantly betray, criticize, and manipulate you can take a toll on your emotional health. It’s a whole different monster if it’s your brother or sister.

That’s why prioritizing your emotional health is crucial.

Just like setting boundaries, this can take different forms. For me, it meant incorporating activities that helped me process and release difficult emotions.

Journaling allowed me to express and understand my feelings, while meditation helped me find inner peace and clarity.

Engaging in activities like sports became my outlet for stress and frustration. It wasn’t a cure-all, but it provided a much-needed safe space for myself.

6. Get Support From Friends and Family

We’re often raised to believe that having a sibling means having support when things get tough. But what happens if that’s not your reality? Where do you go then?

No one thrives in isolation, especially when facing a toxic sibling dynamic. In my case, my husband, close friends, and my cousins became my support system.

Talking to them about what I was going through allowed me to feel seen and heard. They offered invaluable advice, a listening ear, and unwavering emotional support.


Find a supportive friend who can remind you that authentic, healthy connections exist. They can also make you feel valued and understood.

7. Don’t Seek Revenge, It’s Not Worth It

In the heat of the moment, it’s easy to want to get back at your brother for his sibling bullying. But here’s the truth: seeking revenge is a trap that ultimately hurts you more.

It keeps you focused on negativity and prevents you from moving forward.

Don’t make the same mistake that many others have made. Instead, choose the high road. Channel that energy into self-care, building healthy relationships, and pursuing your happiness.

The best revenge is living well and proving to yourself, and everyone else, that you won’t let their negativity define you.

8. Cultivate Self-Confidence So You Don’t Feel Intimidated by Him Ever!

For years and years, my low self-esteem made me vulnerable to my brother’s attempts to belittle me.

However, as I started focusing on self-care, setting boundaries, and surrounding myself with supportive people, my confidence grew.

Now, I no longer feel intimidated by his negativity.

If your sibling seems keen on bringing you down, a strong sense of self-worth is your armor.

By cultivating self-confidence, you allow yourself to thrive, emotionally and physically, regardless of his actions.

Your sibling could attempt to control you, but if you believe in yourself, he won’t have that power over you.

9. Focus On Positive Relationships Around You

It’s understandable to feel drawn to the familiar, even when it’s a hurtful relationship.

But if you have a toxic brother, it’s important to take care of yourself by actively nurturing the positive relationships in your life.

Siblings often share a deep history, but if he becomes a source of pain in your life, it’s okay to cut ties.

I learned that it’s better to surround myself with people who uplift me, encourage my growth, and value my presence genuinely.

These positive connections can become a source of strength and joy, reminding you that you are loved and supported.


Spend time with people who appreciate you for who you are and contribute to your happiness. These connections will provide you with a sense of belonging, acceptance, and validation.

10. Forgive Him but Don’t Forget

Forgiveness is a complex journey, and in no way does it mean condoning your brother’s behavior. It just means letting go of the resentment and anger that can hold you back.

It took me a long time to understand this.

Initially, I felt like forgiving him meant erasing everything that happened. But I realized that forgiveness is for me, not for him.

It’s about releasing the burden of negativity and choosing not to let his actions define my present or future.

Remember the past and use it as a learning experience. It can help you identify boundaries and avoid situations that might become toxic again.

You can try to understand his actions without condoning them, and you can choose forgiveness for yourself, even if he may not want it at this time.

11. Consider Professional Counseling if You’re Alone

Therapists are trained to help individuals deal with toxic siblings and the complex emotions such relationships can evoke, like anger, resentment, or even jealousy.

When you seek help from a therapist, you can explore the root causes of the conflict, understand your own psychological needs, and develop healthy coping mechanisms.

They can also help us process past hurts and work through any emotional baggage that may affect other areas of our lives.

This process, sometimes referred to as shadow work, can offer a unique perspective and empower you to move forward with greater clarity and emotional resilience.

12. Accept What You Cannot Change and Move On

Accepting that my sibling is toxic was perhaps the most challenging hurdle I faced.

It’s natural to want to fix things, especially within the family. But the truth is, you can’t control someone else’s behavior.

You can’t choose your family, but you can choose how you respond to them.

Accepting that the situation might not change, however difficult, allows you to move on and focus your energy on building a fulfilling life for yourself.

It doesn’t mean giving up hope or condoning their actions, but rather acknowledging reality and choosing self-care over futile attempts to control the uncontrollable.

Remember, you deserve peace of mind, even if the relationship with your sibling may continue to be strained. Choose not to let their negativity define your happiness.

13. Stay True to Your Values and Your Integrity

Living authentically, even in the face of challenges, is a form of self-respect.

Even if your sibling may get frustrated, become angry, or try to manipulate you into reverting to old patterns, don’t compromise your core beliefs just to appease him.

It might seem like you have no choice but to follow the same path of negativity, but that’s not the reality.

It’s okay to have different perspectives and boundaries within a relationship.

I realized that by choosing integrity and staying true to what I value, I not only protect myself but also set a healthy example for future interactions, whether the dynamic between me and my two siblings improves or not.

Why Should You Protect Yourself From Your Toxic Sibling?

Protecting yourself from a toxic relationship with a sibling is crucial for your mental and emotional well-being.

Just like any harmful relationship, staying in a toxic dynamic can drain you, breed negativity, and hinder your personal growth.

The key? Letting them know you won’t tolerate their toxicity anymore.

For me, recognizing the toxicity of my brother’s behavior allowed me to take ownership of my well-being and start making choices that protected me from further emotional harm.

I started to set firm boundaries, limit contact, and prioritize self-care. Let them know that you’re not able to continue engaging in unhealthy dynamics.


Prioritizing your mental health is not selfish, but necessary. By taking these steps, you can create a space for yourself to heal and thrive.

It’s OK if You Can’t Stand Him, I Can’t Stand Mine Either

Figuring out what to do if your brother is toxic is tough, and sometimes, sibling estrangement might be the only answer.

Trust me. There’s no shame in deciding to cut someone out of your life, even if they’re family, if their behavior harms your well-being.

So, once you recognize the signs of a toxic sibling, start taking steps to protect yourself.

You deserve healthy, supportive connections, even if they don’t come from where you expected.
