7 Warning Signs You Have A Toxic Sibling

Author : zanem Jassym

Do you have a difficult relationship with your sibling? Itโ€™s not just sibling rivalry but their attitude towards you that makes you fallout. Hereโ€™s how to recognize the signs of a toxic sibling and how to deal with a toxic sibling.

Siblings are not always the best part of growing up, especially if they are toxic.

When people talk about toxic family members, they usually speak about a dad they donโ€™t get along with or a mom who tries to ruin their lives. But toxic family members can include siblings, too. And it can be incredibly upsetting.

Getting along with siblings is difficult as it is, usually due to the well-known โ€œsibling rivalry.โ€

For folks with toxic siblings, it can take a lot of work to keep a relationship going. And a lot of times, you find that you donโ€™t even really want to try.

Here Are The 7 Signs Of A Toxic Sibling Relationship

1. The Relationship Is Based On Abuse

Abuse comes in all types and forms โ€” mental, physical, sexual, verbal, and emotional. It can really get to you and leave you feeling like youโ€™re unable to handle your own life.

This was the case for the anonymous poster on Mamamia.com, whose sister made them feel like a total screw up for almost forty years. โ€œNobody can upset me like her. Nobody can leave me feeling like such a loser,โ€ they wrote.

Even though you can simply chalk this up to mean words from a sister, itโ€™s still abuse. The poster put up with it for decades, saw no change, and finally decided to cut ties. Thatโ€™s not always the required course of action, but itโ€™s important to respect how you feel and whatโ€™s best for you.

2. They Give You Anxiety

Itโ€™s normal to feel a bit of anxiety around family members, especially the ones you donโ€™t see very often. Maybe youโ€™ve struck a nice balance between having a sibling in your life, just not too often. And thatโ€™s OK.

Itโ€™s when the anxiety gets out of control or becomes pervasive, that problems can ensue.

As Genevieve Shaw Brown notes on AbcNews.Go.com, โ€œWhen you are living in constant anxiety never knowing or being able to predict how any engagement is going to turn out, it is time to love yourself enough to let go.โ€

3. Your Sibling Is Too Crazy To Talk To

You may have an eccentric sister or a weirdo brother, and that can be quite charming. But when every interaction with a sibling leaves your head spinning, and you find yourself in cyclical nonsense arguments, then you may be crossing over into toxic territory.

According to Shaw Brown, โ€œWhen crazy-making, no-win games dominate the relationship such as the silent treatment, blame-games, no-win arguments that spin around on you, there is no point in continuing in this battle.โ€ When this is the case it may be time to cut ties, seek therapy, or at least to back off for a while.

4. The Rivalry Is No Longer Cute

My brother and I have totally different career paths, and it used to be a point of rivalry (at least for me). However, now that weโ€™re older, I feel so much pride when I hear of his accomplishments, and heโ€™s always happy for me, too.

But some siblings never grow out of that competitive phase, and it can cause some real problems as adults.

According to Jane Mersky Leder for Psychology Today, โ€œWhile few adult siblings have severed their ties completely, approximately one-third of them describe their relationship as rivalrous or distant. They donโ€™t get along with their sibling or have little in common, spend limited time together, and use words like โ€˜competitive,โ€™ โ€˜humiliating,โ€™ and โ€˜hurtfulโ€™ to depict their childhoods.โ€

If your sibling reverts right back to their childish ways the second they interact with you, that might be a sign of some toxicity you donโ€™t want to be a part of.

5. They Only Bring Bad Things To Your Life

If youโ€™re questioning your relationship with your sibling, think back over your history and try to remember any good they brought to your life.

If itโ€™s all just kind of neutral then you have nothing to worry about, because not everyone has an amazing relationship with their sibling. But if itโ€™s all doom and gloom, fights and arguments, then take some time to consider how important the relationship is to you.

6. They Try To Ruin Your Relationship With Other Family Members

Itโ€™s not uncommon for family members to stir the pot in order to get people to turn on each other. Call it a love of drama, or call it downright crazy โ€” itโ€™s bad any way you look at it.

So consider cutting ties with a sister who tries to turn your mom against you, or a brother who doesnโ€™t want you visiting his kids. Itโ€™s not healthy for anyone.

7. They Are Selfish

In a perfect world, family members would be there to help one another no matter what. Moving? Got it. Setting up a wedding? No problem. And yet some family members, including siblings, can peace out at the most inopportune moments. Think about how it makes you feel if you have a sibling who has never stepped up to help when they were needed. The answer is, โ€œprobably not very good.โ€

Some toxic relationships can be repaired, so donโ€™t lose hope of patching things up with your brother or sister. But also donโ€™t be afraid to move on without them in your life if you decide thatโ€™s the right thing to do.
