I can't find a job and I don't know what to do about my situation

I'm currently in a crisis right now where I can't find a job. I don't have much to put on my resume since I barely managed to graduate from high school and I currently don't have the finances to afford further education such as obtaining a degree or becoming certified. I'm incapable of masking in order to seem like a "normal" person so interviews often go rather poorly, especially since I have a major RBF. I've been told by many people that social skills require experience, but no matter how much I interact with people, I can't seem to learn how to act like everyone else does. On top of all that, a lot of entry-level positions require a lot of standing or physical tasks which I can't do since I fucked up my body at my last job which was at a fast food restaurant. I've tried applying to remote jobs as well, but no luck there. I also have severe mental issues but can't afford treatment.

I know homelessness isn't the end of the world, but who knows if I'll ever be able to get back on my feet again? Not to mention how dangerous it is for autistic women. I'm genuinely considering ending it all because I don't know if there's any other options for me at this point.
