The family should consider themselves lucky they were able to have a funeral Mass for the kid. For most of its history the Catholic Church prohibited funeral Masses in cases of suicide. That only changed when modern research involving mental illness added a degree of uncertainty about the willful nature of a suicide victim's actions.
The Catholic Church is corrupt beyond belief. Same for the public school system.
I think one must be mentally ill to commit suicide. I could be wrong but if you think hard about this, I think it’s not even debatable.
Same with Jews and suicide. Until the 20th century, Jewish suicides could not be buried in a Jewish cemetery. Now they are considered to be mentally ill.
I wonder if this was the family’s attitude all through their son’s life - that they could not bear to hear anything that they didn’t want to hear and became hugely upset if anyone went against their wishes. This type of dynamic leads to anxiety, and then depression.
