even if you aren't suicidal, you can call their hotline. Call 1-800-273-8255.
maybe consider joining the military. if you have a high school degree, no criminal history or medical issues, you should be qualified to enlist, but you still need to pass the ASVAB test (basic high school knowledge), and be relatively in shape. they have hundreds of jobs that aren't all combat or infantry related, and plenty can easily translate back into the civilian world. it's only four years long, though some jobs require six, and you get paid training along with it.
do some research, then contact a recruiter for the next steps. if you can't physically go to a recruiter, often times they will come to you if you are seriously interested.
