What should I do?

I’m a 18 year old guy who recently dropped out of Marine bootcamp because of suicidal ideation. I tried applying to many jobs around me but I would get rejected every time. I’m not that great academically either since I graduated with a 1.8 GPA, what should I do? I really want to do something with my life but I feel as if the medical fraud in my military record is hindering me from finding employment. I tried applying to other branches as soon as I got out, but they couldn’t really help me. What should I do in this situation?
