Hello, so I'm the daughter of someone who was abusive to my Mom so my brother, my mom, and I left him when I was 3.  The issue is, I rarely contact my Dad, but he is an alcoholic and when I see him in the morning when he hasn't had much to drink, he is totally normal.  However, he often leaves us messages at night and he sounds so delusional.  Talking about religous things and sounds paranoid.  He also smoked weed throughout his teenage years.  I asked my mom when he started being like this and she told me when he was around 39.  I have an anxiety disorder so this chance of me becoming like this is terrifying me.  I'm 19 right now.  I know that you can't diagnose him for me, but should I be worried about this being hereditary? and do you believe this could be schizophrenia?
