So I had a break up I was in a relationship for more then 4 years and the reason was that I'm not stable mentally ,I tried my best to work things out but didn't work. I feel I am not sharp in head I need help where I be quick in things, so now I work a during the day for 9 hrs but even though I'm very tired I don't get sleep in the night and I'm going through a lot of stress and I don't know wat to do.
