Hard to say if it’s corrolated or not. The whole nature vs nurture thing is kind of put on hold with sz and its related issues, because it’s been said to happen from both, not just one of the two.
I had a great grandmother who was sz, but no one else in my family has any signs of it, outside of my aunt, whose thyroid is failing so horribly it’s tough to say she’s sz or maybe just has thyroid problems (which she won’t take meds for). She believes she communicates with dead people and is a highly powered clairvoyant who can have her way whenever she wants, despite being proven again and again that she cannot have her way.
Me personally, my biological father cheated on my mom when I was a baby, so outside of a handful of visits, I didn’t really know him up until I was 10. I had a step dad who was taking care of me, but he stepped out of the picture for my biological dad because he felt it was the right thing to do.
I moved in with my biological dad for a few years, and he and my step mother are just twisted beings, so they made life very hard on me. They tried to replace my mother and step father and it caused problems.
I would say for me, I probably wouldn’t have developed sz if I hadn’t been stunted, stripped of dignity, and made to feel weak and forced to be dependent on my father and step mother. If I hadn’t moved back in with him, I’d probably be running my own company right now.
Is it fair to say he’s probably responsible for me developing sz? No, but I did not have symptoms of sz until shortly after I moved in with him, at the age of 12. Things only got worse for me over the years because of him and his inability to show affection in a meaningful way besides “That’s my kid” when we’ve been out together.
Recovery is a step by step process, but identifying triggers and preventing them from being a part of my life is a big part of why I can present as normal to most people. My biological father is a trigger.
This was really long and I’m sorry, but yes, I feel that abusive parents can contribute to developing psychosis, especially if there’s a genetic history in your family.
