Sigh, I'm so sorry you have to struggle with this. I can totally relate. I'm (according to my pdoc and to a certain point I agree) psychotic and I'm afraid of telling my dad because I think he will deny it all. My mother was okay, worried, like you, but she believed me.

Everybody says it takes some a while to "accept" schizophrenia etc. I'm not sure, but I hope so!

How does he see your son's symptoms? I hope he knows there's something wrong with him, that (presumable, since I don't know your son's situation, but seeing he has 10 symptoms it seems pretty serious) he can't function properly without treatment.

Well.. This is not much, but it's all I can say. Your son is very lucky to have a mother like you who educates herself. That is definitely going to help him. All the best to you and your son.
