pain, hurt misery....sad, crying, hatred

suddenly I feel like crying when I came across a profile in FB. Suddenly it brings me so much pain and misery, why I need to be sad coz of him, I tried to hate him, and I really I thought I manage to do that but when suddenly I came acroos his profile why I feel so much pain. hurt and I really want to cry out loud. I hate this, I wanna be strong, build a new life, start all over again but it's hard, damn hard till I'm not sure if I can ever get over it....
