Suicidal tendancies, as an aspect of mental health and mental health afflications, such as depression, schizophrenia, borderline personality, manic depressive etc can run in in families.

Suicide itself is just an act and if it is found as a pattern within a family, it is likely because there is a commonly inherited mental health issue or chemical imbalance.

I have always wondered that myself. I have been "on the suicide train" since the age of 13. I "got off the train" a few years ago. Curious because my mother attempted suicide when she was 16 and now at the age of 39 her death is unknown and my father did commit suicide. Coincidence or just a messed up family.?

It did in my biological mothers family. Her and a sister a few aunts and a great grandmother all had commited suicide. :)

Yes. My boyfriend committed suicide about a year after his older brother did so.

Well, hopefully suicide in the mid teens doesn't.. older than that, it might be possible. Mentality and certain types of moods are certianly carried in your genes, my dad is also very dysfuntional when it comes to communicating when other people, just as me. Some of these types of mood and behaviour patterns might spur suicide
