How do I find the will to live?

Ok so I’m 21 & I got my associates in sociology but going to school and working was so much that I finished there. I’ve taken a gap year which turned into another year now because I didn’t think I would live this far. I work a serving job and I am treading my feet in that but to work another job I’d need to make the same I do serving and I have no motivation to work a job with more hours and go back to school so idk what to do.
