Hun, here's a hug!! At 30 your are entitled to your own life. And not to be mean or anything, but you are also responsible for your own happiness as well. That means not blaming your mother for your choice to stay in this dysfunctional household!

Do what it takes to move on..

So she has issues. It's her life...she survived before you, and she will after you leave. Again, I don't mean to sound ruthless or harsh, but don't get "guilted" into staying!! This isn't healthy, and frankly, you could be enabling her illness. Please get some counseling because you deserve some happiness! Good luck.
