Girl,
You are way ahead of me. I didn't seriously start identifying the pain and pressures of my alcoholic family members until I was in my 30's.
You will be fine. Your road will be a little bumpier than some peoples' because of what you've had to deal with, but you can still live an incredibly happy life if you make the choices -- and only the choices -- that will move you toward it, and none of the choices that will get in the way.
Hugs to you -- take care of yourself
