I am not sure what went wrong. Obviously a complicated situation.
This question of teen suicide is something I have researched for several years, as my kid's high school had a sudden surge of sucides in a few year span. * It was tough for my kids because both of them had friends who killed themselves in that span of time. My son's classmate drove off a Malibu cliff, daughter's friend hung herself in her family garage.

I went to a few community events, for parents, about suicide prevention, etc. The takeaway for me was that all of this 'knowledge' and data, that children have at their fingertips, can be too much information for a young mind.
They can be overwhelmed by 'traumatic news' ---like upcoming climate change, and socio-political struggles, and economic uncertainties and global warfare and FEAR in general.
They also can be emotionally overwhelmed by the social media machine and feel helpless and unable to cope with the ugliness it can create.
On top of that, violence and




and things like that are saturating the internet and too easy for young minds to get into.
The combination of all of the above can be too much for a troubled kid, perhaps one whose family is going through a crisis as well. Kids fall through the cracks, and feel alone and isolated, even when they have friends and family who love them and think they are fine.
