It's my understanding that (at least since the song was made) she went to several rehabs...
I keep thinking about Amy's goddaughter, Dionne. She was so close to Amy and must absolutely devastated by her death
This is why I hate drugs... it destroys not only yourself but the relationships with those around you. A 10 year old girl that I counsel is currently dealing with her uncle (she totally idolizes him) going to rehab for drugs and she's completely crushed by the fact that she won't be able to see him for months. ::sigh::
