From someone with absolutely no use for the 'methods' used in these places, I was 18, I had no real 'addiction' to speak of except for being considered depressed, suicidal, and bulimic, NONE of which I was. In some circles for an 18 year old to be a tad on the morose side is fairly normal, and I like to eat, always have, and after I finally made it out, the vomiting turned out to be an ulcer, not, as most everyone else thought, self inflicted.
Yes, I occasionally drank a beer when out with friends, and I'm aware that's illegal, but some people do have the capacity to drink socially, know personal limits, and stay within them. I drink socially still, but I don't get drunk, and I don't like drunks. I occasionally also partake in other "adult" activities, however again, I'm aware of my limits and stay within them.
No, I'm not currently in AA. At 27, I'm a college graduate, I have a home and a family, I'm fortunate enough to have a good support system now, and although I have faith in higher powers, I don't particularly ascribe to any single organized religion. I consider myself happy and successful, despite the mind fucking I got in years past. I was there 18 months, and it's taken the love of my husband and seeing my son's eyes to help me get over the past, and resolve to not ever put my child through the hell I was placed in.. no matter what good intentions I might have.
Is that a thorough enough answer? Hope so.
