My brother has been having manic episodes since he was 17 (he'll be 21 this year). He and our mother live alone together. He's been in and out of the hospital (sometimes the episodes make him say dangerous stuff, not sleep for days, etc.) and he's come out with a different diagnosis every time (bipolar, schizophrenia, etc.) He refuses to medicate or get into therapy/support groups. It's taking a major toll on our mother.

When he's not in an episode (they last weeks), he's often depressed/irritable. He recently dropped out of college halfway thru, and spends 12+hrs a day playing Fortnite; barely eats or sleeps. They both live in govt-assisted housing/foodstamps. 

We're afraid this will be his life; living with mom and rotting in his room. We can't afford real healthcare and feel stuck.
