Suffer!

Recently really very tired~need to care this and that things~make me very suffer~I hope to stop it soon~After he entered my life, sometime my life is colourful, but sometime is black or grey in colour. I lost many best friends. I lost some freedom. Anyone can tell me? Why will I feel like this?I'm confusing now! Really don't know what can I do. I feel want to cry. Anyone can tell me? Why will I choose here to realise my feeling? I'm very sad now. My friends don't me anymore. Always fu hin me. Very sad.
