Advice needed please

Hi everyone! not sure where to begin, or where im actually supposed to post this. Anyway my bestfriend (whos a guy/ my boyfriends cousin) has schizophrenia. He had a psychosis episode and we found him 4 days later in jail. we got him out & he was in a mental service ward for a few weeks and just got out yesterday. He is very spacey and not his normal self ( they said that his shot can cause that) but we aren’t sure what to do. He was living on his own and still has his own place but he doesn’t want to stay there alone, he said it scares him. He is 21 and only has my boyfriend and I…we cant take him in & care for him either. We are looking into a possibly group home. Does anyone have advice? or anything to tell me that they think might help? Thanks in advance
