I am just coming out of a stretch of depression. Not only that, I have had a a bout of irrational fear of death. These symptoms are a product of my upbringing in this cult. You can escape this cult. However, the mental torture can stay with you for a long time. I hope one day I can get over this. Or at least alleviate these feelings to an extent that I can live a normal life.
So yes, by my own experience, I can truly say that such mental illnesses as OCD are a product of being in a high control cult.
