What do I do??

I don’t know what to do anymore I have this intense anger inside of me that is unreal. I am suffering so much and I have no hope left any more. I am 24 years of age and I have been suffering since I was 13 with severe mental health problems. I am diagnosed with schizoaffective disorder but my psychiatrist doesn’t even know if that’s the correct diagnosis. He also thinks it could be bipolar and to be honest it could be anything I don’t know it’s so complex that I’m really hard to treat. My psychiatrist even said I’m treatment resistant. My whole mental health team seem more focused on getting me to get a job rather then actually look for what the heck is even wrong with me. I can barely even leave my house. I have social anxiety, low self esteem, ocd, anger issues, general anxiety, severe depression along with schizoaffective disorder (which I think is an incorrect diagnosis). If I went into details about every thing wrong with me I’d be writing for ages and I don’t have the energy for that. I literally have the energy to do nothing and I’m only 24. Taking a shower is a huge task for me and all the everyday things people do with no thought or bother are extremely difficult to me because I have literally no motivation, no energy, etc. I also deal with everything in anger like I just get angry that I’m feeling like this instead of sad or crying. I get angry and I punch myself and hurt myself until there’s lumps and bruises on me or I’m walking with a limp. All I do is search the internet for answers as to what could be wrong with me. Whatever is going on with me it’s very complex and that means it’s very hard to get to the bottom of it. I can’t live like this anymore. If I wasn’t so scared of dying then I would of killed myself by now. I’m also turning into such a shitty person who has an attitude with everyone and I’m starting to not give a shit and that scares me because I want to be a good person. There’s so much more I want to say but I can’t even think straight and everything’s all jumbled in my mind. I’ve tried medications and nothing is working. Antidepressants would work for me for a few months then all of sudden I’d start feeling like shit again which is another weird thing. My psychiatrist doesn’t know why that is. I just don’t know what to do. I’m crawling out of my skin I don’t feel like I can keep this going any longer but at the same time I have to I’m so lost.
