My family is sort of dysfunctional and it's beginning to seriously annoy me...help, seriously?

If your old enough, take your dog and DISINHERIT your family. Find a job, a cheap apartment and make something of yourself. Get a new life. A fresh start. That's the best I can suggest, but hey, I'm no psychologist. You need more info. How old are you? Can you get into college and make something of youself. The part that makes me most angry is that they wanna sell your dog to get another one. I'm so sorry about your situation. I hope you'll sort things out.
