You know Ainslie, my family sucks too. They are not the family that I want, that's for sure. But, like many people here, I have 'made' a family of my own. I have a couple of people close to me who I consider family, plus I am blessed to have my husband's family, who are amazing people.
My advice would be to stop wishing for things to change in your family situation. I say that, because I spent so many years wishing and hoping for things to change, and getting more and more depressed. Look to your friends to be family for you. And, don't forget, we are all family here at SR.
