There is a Schizophrenic section on Medhelp and the posters may be able to help you on the antiphyscotics medications and give you a understanding of what your son is going thru. This must be very hard for you. Please don't forget to take care of yourself.
Your sons fears of being locked up should be respected unless you want him to fear talking to you.
Letting him move back in with you is a nice thing to do. When i tried to commit suicide, my family stopped talking to me. What is the obvious solution? More suicide of course.
I think that you both need to get honest with his team. You are doing him no justice by enabling him to keep up the front. That is why he is there, to get help. There are all kinds of meds, it could be a simple med change that would make a difference in his thinking. He is not in therapy? Therapy in conjunction with meds is proven to be the most effective form of treatment. Good luck to him.
first get him into therapy before coming off the meds. this really needs to be supervised to taper off
I will keep you and your son in my prayers. while you go through this difficult timeLet me know how things progressf or your son.
