My family hates me..

So I've had a lot of personal family issues the passed 7 years. I had been emotionally abused by my step dad, and then my grandma. I would constantly feel like nobody cared, i was not wanted, etc. And finally I thought I had gotten out of that when moving in with my dad a little over two years ago I belive. Everything was great the first couple months. But soon it all went down hill. I was back to being called names, and constantly being put down. This has been going on since then and I don't know how much more I can take. I don't have many friends I can talk to about this. My boyfriend tries, and I really appreciate it, but he doesn't really understand. I feel so alone at times. So unwanted. Not good enough. I feel like life would just be better if I weren't here.
