Seems like multiple perspective - chicken or egg.
I have watched as a family member went off the rails on a CRAZY TRAIN due to the death of a child.
Went to church and alienated self until asked to leave. EXPECTED THE PREACHER TO HEAL - MAKE HER STOP HURTING - BECOME SANE.
A psychiatrist was no good because he was supposed to tell her to make the pain stop.
Now she is an expert at why everything is bad. Why the world is in total ruin because everything that our parents and their parents (figuratively-prior generations actually) did to screw up the world and leave us in this terrible mess.
It is impossible to be happy because the scum of the past screwed it all up and left it to us.
