Shit, I remember back when I was 17 and thought I had it bad, just get a hobby, workout, hang out with friends, make friends if you dont have any, learn to drive, ride a horse, swim, play sports, get a gf, theres literally so much you can do at 17 and itll all be super exciting because itll be a new experience. I'd do anything to be 17 again with the same problems I had at 17, those were the best days of my life. If you think you have worries at 17 just wait until you graduate and are all of a sudden in your mid 20s with a job and real grown up stuff to deal with. Enjoy your time while it lasts bro
