I've tried so hard to be happy but it seems like I'm not meant to be happy. I don't feel sad all the time though, I usually have like two or three days of pure happiness but what comes after makes me dread those happy days more than I dread the sad days. The major problem is I can't give a valid reason why I feel that way. I've tried talking to my boyfriend and my sister about how I feel and how I sometimes just want to end it all but I've never been able to fully open up because I don't know how they'll react to it or how it will affect their own lives. I know I need help.
