Does self harming behaviour run in families ?

Self harm itself is not inherited from your parents. However, certain disorders that can lead to self harm are. Anxiety disorders, depression and BFRB's are more likely to be present in children of people that have these conditions.

It can run in families. Often times Anxiety, Depression, etc. runs in the genes of family. Which can definitely lead to more. If you hear stories of family or friends that cut, often times you will think of it as a getaway as well.

No it doesn't in my case. It depends on how do you take things in your view because you can be optimistic or pacimist

To give you a short answer: It's very possible. As kids, we look up to our parents. They're our best friends when we're younger. When we get older, and understand the world more and more; you could find out that a parent or relative is harming themselves because they could be sad, lonely, angry, or any negative mindset. When we're teenagers, this seems like the end all to problems. When we see people we look up to doing things, we want to do those things too.

I do not believe the behavior runs in families. I believe it stems from the individual and their surrounding relationships. With experience, I can vouch that for me it was stemmed from self-esteem and the relationships I've had.

I don't think so, every human has a different way to cope with things and or coping skills don't get passed down, unless it's learned behavior
