Im a nervous wreck

I quit my job. They cut help there theyve only had three people on the hall instead of four. It was a nursing home. I just couldn't do it. I was too tired to do anything, one of the residents warned others that the administrator was told to cut the buildings budget. But now Im stuck unemployed scared as hell of annoying my family with my unemployment. Ive already tried applying to three call center jobs. One already struck me down. Theyre probably looking at my history and thinking to themselves that I havent been in the sit down industry since 2016. I posted that I had really bad burnout and insomnia so bad that I hyperventilated at work in a forum about business on an online place called fishbowl and some random troll posted on it saying that I was weak. I want to cry but nothing will come out. I blame this mood stabilizer. There are times that I want to do away with myself but I know it stops me. My nerves are fried and I cant even help my homeless best friend. He was diagnosed with Parkinsons. I am just glad that he checked himself into a mental facility. He did have a psychotic breakdown and attacked me back in January. I was more than likely over my head. I cant control his drinking only he can! All I can do is apply for jobs and try to reset my sleep schedule for now. According to the social worker that was at the hospital Im going through a loss. Maybe I'm still in denial that I have lost a friend. I don't know what direction to head all I know is that I can't just dart across the united states to be with him. He needs to be in a mental facility and it probably would be worse on me to be homeless.. I probably would be completely nuts being homeless.
