Hodaya! This is so exciting! You are probably going to be fantastic in any area of health care, because you have a very special experience and insight as a patient yourself, and so dental patients will really appreciate your manner with them, which I am guessing is going to be warm, caring and sensitive. And that's in the medical area of dentistry that is notorious in any country for being masochistic! Whatever dentist you work for, you are going to be their greatest asset because the patients will want to come back (and nobody wants to go to the dentist)!
But this is probably the best time you've had in years, this feeling that you can start a new life! You can do the studies too, don't feel afraid of that. It's the chance to see how much you really can achieve, step by step.
