Yay! Sounds like you took a very positive step in the right direction.
If I can make one suggestion, do your very best to be PATIENT with the process. I don't know a darned thing about Topamax, but from what I understand, most meds take awhile to be fully effective. And even when they are fully effective, there is a lot of work ahead of you. I DO believe, based on my experience and observations of other people, that addictions totally stunt maturity. You can't really learn and grow from your experiences while you are whacked out and escaping from reality.
Proud of ya--keep up the good work.
