I’ve Exhausted All My Options

So, since 2011 my older brother has been having symptoms but has been diagnosed with schizophrenia, bipolar disorder and ADHD, in my opinion psychosis. I’ve been to mental health court with him, tried several programs and various medications. Me and mother’s last resort is always the hospitalization. He needs therapy, he hasn’t been on meds in 9 months he was fine but not he decided to get back on meds but doesn’t take all of them. He’s an alcoholic, beer consumption everyday! He always blames me and my mother if he can’t find something he lost. He has angry issues, blast loud music and in his car I’m surprised neighbors don’t call the police for noise complaints. It’s exhausting going through this all. I can’t allow my oldest brother who also in a program to come over because my other brother thinks he steals his stuff which isn’t true. I can barely sleep most of the time, I sleep over my bf house just to get a rest, on top of that I’m my mother’s caregiver she has metastatic breast cancer. The stress is unbearable. Idk what to do anymore except deal with it as I been dealing with it sadly.
