Dexedrine? Adhd? medicine? HELP!?

I take dexedrine to help me study once in a blue moon, but i'm taking a liking to it. It really helps with my anxiety, depression and keeps me focused on things in my life that I should be focused on. Im in university right now and find that I often can't bring myself to do anything since im so lethargic and lazy and get distracted by the little, unnecessary things in my life that frustrate me. Does any one take these regularily or does anyone know if it sounds like it could help me? I read somewhere that dexies are dangerous since it is technically speed. Dexedrine is for ADHD by the way. But i feel it really stabilizes my mood and keeps me focused on the important things. I'm actually much more rational, strong and levelheaded when im on them rather then the emotional, depressed paranoid mess i usually am.
