I think it's purely genetic factors which are responsible for the most severe of mental illness like schizophrenia. Then again if factors like bad parenting come in place, they should contribute to less serious disorders like anxiety (which may in fact turn life-threatening later on) and they the physical/psychological/sexual abuse should take place in early childhood (before the age of 6.)


In my case I have infantile injury. Later asphyxiation. Later abuse and then isolation from society. Which led frankly to my utter destruction.
