Someone close to me has recently been involuntarily admitted because of what can only be explained at the moment as a mental breakdown. There were underlying issues of depression and anxiety that lead to insomnia and seems to have lost their mind. He is out of hospital and refusing any medication but is a little more clear headed. Now explains that when the breakdown happened he can only describe it as feeling/being catatonic. The remaining effects of this whole ordeal are trauma from an aggressive involuntary hospitalization and extreme paranoia. Every single thing is suspicious. Me wearing all black is suspicious. The other cars on the road are suspicious. Having sushi for dinner is suspicious. It recently got worse when he started crying saying someone is watching the family and going to kill his mother and he’s scared. 

I think he might be schizophrenic. He wants to get better but refuses help and meds and wants to do it on his own and naturally but it seems this is too severe. 

I think it may be stemming from being sedated at hospital but he keeps saying that he knows he isn’t acting like himself and thinks he was dosed and is now being framed by someone. 

How do I talk to someone like this? Gain the trust back and convince them to get medical help
