My died kill himself late 2019 right before the covid epidemic and I have been in a down hill spiral since. My grandma got covid and passed. I lost my favorite and best job. And my car broke to the point of no repair. Had to get another car from a friend only for it to break and the repair cost just as much as i paid for the car. No matter how much I tried I could not keep me and my fiancee 23f afloat. We lost our apartment. 
Had to move in with fiancee mom. Was not in a great head space, but I was trying. Spent the whole year trying to manage my mental health and my life in general. Then my uncle got covid and passed. On the car ride back my mother disowned me and ditched me in another state with no real way to get home and it has been no contact since. 
I cant work standing for long times because of medical reasons so most jobs are out, but even then i still did those jobs. I worked kitchen and at menards despite my feet. Then when I was just getting on my feet I got kicked out. My fiancee did not because it was her moms place. 
Went to the hospital for a few days because I wanted to unalive myself. Got out tried to get shelter got into the overflow. And then my fiancee said she needs a break because shes going trough things as well.
I'm homeless, jobless, carless, broke, and mentally broke. I really have nothing left to lose and want to die. I have no idea what to do next. I'm sorry that my efforts were not good enough and I dont know how to be good enough. Everyone I've gotten close to has either died stopped talking to me or ghosted away. Help. Please.
