how about taking up some work as a volunteer in a hospital or any other place …I am sure it will help alot ! I recently joined Shaukat Khanum Hospital Group on Facebook , there so many youngsters are working as volunteer and each one of them has shared his/her experience.
Find some activity , join a library or a club , go out with friends & have fun. Live every moment of your life , don’t spend it thinking about someone who didn’t care about you or your happiness …what good will you get out of it ? this way you only end up making yourself suffer even more . I know it’s easier said than done but it’s not impossible.
