Early Menopause

I'm about 21 years old and I've basically been told by my doctor that due to some health conditions I'm probably experiencing early menopause. This breaks my heart because I have been hoping to be, along side a strong independent and innovative woman, a mom some day to kids of my own. Not that I wouldn't be happy to adopt, however, just it's a part of my self that I'm struggling with and grieving at the same time, and I was wondering if there was anyone else (my age or otherwise) who might be as well?
