I'll probably get nailed for this, but I'm one of those bleeding-heart idiots who thinks that addiction is an illness. Having been there before, it's a tough, depressing thing, but you DO get better if you have the right support systems in place and the willpower.
I was scorned and treated like shit for a while by a lot of people whose understanding and support I could have used, so I'm used to people tossing out callous responses to things like this. Sure I was weak, sure I didn't have my shit together, but the people who claimed to be there for me under any circumstance also ditched me. And you know what? Fuck them. In the end, I didn't need their hate, their sympathy, or their help, and when they came back afterward to give their praise I told them to go pound sand.
At least she's got her family, and on a humanitarian level I hope that she comes out golden in the end - though I can't help but think that her story isn't going to end well.
