Princess,
How are you today?
"We have no Ala-teen here by the way..." - you have more maturity and understanding than some of the adults in my Nar-Anon group - any meetings available? We have had some young people come to our meeting and no one objected, after all you are facing many of the the same issues as the adults - maybe you could take your Mom.......
" I'm really beginning to think that addicts have something wrong with their brains." ......and you would be correct, their brain has been rewired to focus like a laser on just one thing - chasing the next high. It will continue to stay focused on that single purpose until they decide they want to get clean; no amount of wilderness programs or rehabs will ever change that. When S decides she is going to get clean, she will.
Keep coming back,
Jim
