Well defiantly sounds like psychosis. I'm sorry RB. I wish I had some fantastic advice, but I don't. You need take care of yourself first and foremost, I know you know that.

As what can be done for your friend, I have no idea, he really needs help, but how? How long as he been having this for? Is there any breaks in his thinking, does he come back to reality even for small snippets of time? Agree with Trippin, he needs help right away, family, any other services or agencies?

I have had a lot of psychosis. One thing that helps me is when someone distracts me, does a puzzle with me or something like that. Puzzles seem to help calm me down, I dont need to think too hard while doing it, but have to concentrate enough that it takes my attention away from the delusions. The only difference tho is that I have insight into my illness and your friend doesn't seem to. Calms me enough that i can be talked too. I don't know really how you can help them see it either. Except for trying to provide proof or something like that. Like you said it's tricky, you don't want him to think you are also a puppet.

Maybe you should post this in the schizophrenia forum too, they might have some better ideas or help. I hope you can find some help for your friend. Hopefully you will get some good advice.
