So were you ever formally diagnosed? It sounds like you have PCOS (polycist ovarian syndrome).
Yes I've been dealing with it my whole life. The only thing that has worked for me is the South Beach diet, with PCOS it seems that lowering your carbs is the only thing that works to alleviate symptoms. That and exercise.
Also medication may help, such as spironolactone for the excess hair and metformin if you have high blood sugars. Ask for a referral to an endocrinologist, they can give you more information and the proper medication if you would like to go on them.
Basically my understanding is our testosterone is too high, then it causes our ovaries to enlarge, then through some connection this causes us to have issues with insulin resistance in our cells. The insulin resistance makes it much easier to gain weight but harder to lose weight. Hence why a low carb/right carb diet really makes a difference in our weight
