I screwed my life up

Hello I'm 22 female. I'm not sure where exactly to start but I feel like I have no future at all and its all my fault. I never graduated highschool, and I've been working in bars since I was 18, I've been working at this same place for 3 years now but am now getting treated horribly all of the sudden by a newer manager. She has reduced my shifts and I am barely working at all now. I asked her if there is a reason and she brushed me off. I have been looking for any kind of job outside of the restaurant/bar industry for months and haven't been able to get anything since I have no experience in anything except restaurants. I am fully aware thats entirely my own fault and I very much regret it. I can't afford my bills whatsoever and dont know what to do. I was in a position last year where i had two jobs one of them being a bar lead and was making really good money, i had financed my first ever vehicle and made the mistake of getting a 2025. I could very easily afford it at the time but then me and many others got screwed over by that company and lost our jobs. So i am now stuck with very high insurance because its a new car and can no longer afford it ontop of rent and other expenses. I put myself in a situation where I have payments I can no longer afford as I am making a quarter of what I used to. I have no money to get to school. I feel so stuck and like such a failure because of my own actions. People always say "you're young you have time to figure it out" when thats just not true, I cant even afford to live, and what possibly could change in the next few years when I cant even go to school and nowhere will hire me. I have looked into trades like welding but you need to pay for the schooling which I cannot afford. I've been getting screwed by car insurance companies onto of it all. Please dont tell me I screwed my own life up because I'm well aware, I'm just trying to see if its even possible to fix things and how; like what kind of jobs would be possible. I just feel as though I cant come back from any of this and just want to give up. Thank you.
