Terrible job; can’t get hired anywhere else

My job is ruining my health and my life. A week and a half ago I got very sick and was told I couldn’t go home because I’m the executive housekeeper. Every day is a disaster. I keep being told that it’s slow when there’s so many checkouts every single day and people call off constantly. I try to write them up but I keep getting stopped. Today is my only day off and I feel horrible and I have to go in on my day off tomorrow. I have tried to explain this but I just get told it’s my department and either I’m in or out. I’ve been applying for other jobs and I have a couple of call backs but even with interviews I’m not being selected. My work experience is irrelevant to this area and I wasn’t aware before I moved out here for family. I really want to go back home but I have no money or other family that can help me. Even if I go to the doctor I know my doctors note will be ignored. When I put in for pto I get denied most of the time or forced to come in and if I don’t answer my phone they get all mad at me. I either need to move back home or find something else because I’m worried I’ll end up in the hospital. Any advice?
