I know how you feel I had my stress for 2 weeks and the scary part for me was the 2nd time it came back, i didn't have a reason for it. my stress symptoms popped back in one night, and the symptoms were a lot worse the 2nd time. I still have it.
I would suggest that you see a therapist, they can find out what is bugging your mind, maybe it's a subconscious stress or your getting anxiety disorder (hopefully not). See a professional, diagnose what is really bugging you before you hurt yourself.
