Breast reductions!! Advice!

I'm 20 years old and I have had really big boobs since I hit high school. And they've grown a lot since and now I'm a 34 DDD on the balance of being a 34 E. I have always wanted a breast reduction since I was 16. I hate them and they've put me through a emotional roller coaster and pain. I was wanting some advise on it. Have anyone had any breast reduction? There experience? How much it cost? Any information would help me a lot!
