I'm sorry for all that you are going through, but glad that you will be able to able to get a little physical distance by going back to school.
I like Kitty's idea...give your parents a hug, let them know you love them, then go to al-anon for YOU. When we start working on our codie recovery, it often rubs off on those we love and they pick up on it. The main thing is, take care of you.
Hugs and prayers!
