My Family is Broken Apart? Help?

My family has been dysfunctional as long as I can remember, but in the past year even more so. Its like everyone just does there own thing now that I have moved out of the house. Everyone becomes defensive and driven by their own ego, they are all so afraid of listening and just say what ever they feel, now no one is talking to eachother, my mother says she has given up on my sister, I am not talking to my father bc he said some nasty things to me about what a disappointment I am to him and I should have picked a different husband--- there are no boundaries in this family and no connection, none of us live near eachother either, and my extended family is like 5 hours away, never had any connection there either, it was limited growing up bc they are so far away. I used to be the glue in the family that connected everyone, but I can't do it anymore, its just too hard to keep up with everyone's BS. Its always about them, its never about me. Any constructive thoughts? Comments? Suggestions?
