I'm a bitch lol

So. I have a bad home life. As in I get called names like stupid, f*ckhead, c*nt and any other name you am think of. My parents don't let me see my boyfriend very often. We've been dating 5 months and I've seen him 4 times... Recently I got his brother and his girlfriend back into a relationship. My boyfriend is out of school, but his brother and girlfriend go to the same school as me and I sit with them sometimes. They're together in the cutest way, but I can help but want to cry my heart out. I see them together and want to lay on the floor and scream and cry. It's not just them either. I see so many couples around and how happy they are and I feel so depressed and upset by this. I've trie talking to my parents about it but they wouldn't have any of it. Ive arranged to move in with my boyfriend in November, but how do I stop this feeling? I cry almost every night because I miss him so much and I haven't been out with him for nearly 3 months and he lives like 20 minutes away... how am I going to stop being such a bitch and haring on couples?
