i’m not sure what to do

i’ve never made a post like this but i’m not sure what to do. it might help to just vent a little bit but we’ll see. i think this is the worst i’ve ever felt, i just got out of an abusive relationship and i thought things were going to get better but it seems like they just keep getting worse. i had to leave my job because my boss was being shady and stopped paying me so i do doordash full time. I barely make enough and im severely in debt, my rent is due and i don’t have enough. if i can’t pay then ill be living in my car and i genuinely don’t know what to do. I’ve been applying to hundreds of jobs but only got a few interviews that i didn’t get the job for. i just don’t know what to do anymore and my mental health just keeps getting worse and worse. i feel like the biggest failure ever, and i don’t know why it feels like no matter what i do it never ends up going the way i hope.
