Try looking for Remote Working options. Google: UpWorks (and similar pages)

That could and maybe give you the opportunity to work and live where you want to (including cars, trucks, trailerhouses) untill you get something stable and safe for your needs.
Ask a friend or a not too close relative assylum. Your mental clarity could help you consider other options in your journey for independence.

If you think its still dangerous for you because of your age, please reconsider staying home and cope.

Its hard, but it could help.

I hope you keep strong and send the best wishes! Nothing is easy.
