30 year old female in menopause...Help?

I am a 30 year old female that was just told that Im going through menopause. I am going to my gyno this friday to try and see what to do for this problem, and to find out why. One possiblity is that I just went through a traumatic experience with losing my left leg to cancer. Another problem is that most doctors will want to give hormone shots for this, but because of a disease that I was born with called Neurofibormatosis I shouldnt have any major hormone changes as it can cause tumors to grow in my body! Im a mess I know. But my question is does anyone have any advice on menopause, and has anyone else experienced premature menopause? Thanks!!
