trying2fly,
We're all here for you to rant, rant away!
It is amazing the emotional energy WE ALL go through with our alcohol/drug dependent loved ones, that is why we need Al-Anon, places like this such as SR.com, good friends, the Good book, and strategically placed punching bags throughout our homes to punch when we are reeling from the effects of the alcoholic in our lives.
Hang in there, focus on you, not the crazy stuff your AS is doing, or how your parents enable her, or any of the other stuff. I know, easier said then done sometimes, but it does work, trust me, been in your shoes as well in dealing with my AS. I used to flip out because my Mom does the same thing, they will never hit their rock bottom to seek help. My sis has been sober about 2 months now, it was after my Mom hit her rock bottom and realized her "kindness" was killing sister, not helping and sister finally asked for help on her own.
Take care and focus on what you can control.
