I agree with some of these gals: second opinion, maybe 2-3 second opinions with different types of doctors, and you should definitely speak with an endocrinologist. I actually thought of the pituitary and issues as well. My father in law actually had a little tumor which made him hold onto excess weight and grow 'man boobs', his nipples were always tender and erect, and it messed with his emotional state. He took a medication to shrink the tumor and eliminate it, now he's losing tons of weight. He doesnt have problems with his nipples anymore either. His emotions are better now too. The tumor was causing high levels of prolactin.
It sounds to me like PCOS, but this could be linked and be the root of everything. If you jump to removing the ovaries you may end up losing even more control over your health. Menopause is no fun, and menopause that is initiated without a bit more of the facts would be hideous and possibly unwarranted.
