Thank you all so much. I know it can be done with time and a substantial amount of effort and impulse control. Alcoholism, drug addictions, and mental disorders run rampant in my family...so I guess I shouldn't be so shocked that it happened to me too.
I also have a question: Is there a certain forum, or perhaps a way, to find others that are near my age to talk to? It's helpful talking to everyone that is recovering or trying to recover, but it's also nice to talk to others who are doing this while trying to get back on track in school and most likely don't have the financial means to support this habit.
