Hi Liz, It sounds like you are having some pretty significant symptoms caused by lack of hormones or hormone imbalance. If you had your ovaries removed at age 31, this would be pretty late for symptoms to start IF you haven't been on hormone therapy in between. If, on the other hand, you kept your ovaries, you could well be experiencing the very typical symptoms of your ovaries normally shutting down. The heating up and not sleeping due to night sweats are often caused by low estrogen and the anger and sleep issues are brought on by progesterone lack. The 2 symptoms which I can't tie to hormones are your chest pain and seeing stars. These do not sound normal and I would definitely encourage you to see your primary physician to be evaluated.
I completely agree with the first answer from Toni about the value of sharing your experience with other women. Nothing is more curative than the support and information-sharing that you can get from women who have experienced these issues or those who are in the same boat, trying to find their way as you are. I also strongly encourage you to seek out a provider who specializes in menopause and hormones who is willing to spend the time working with you to a solution. Best of luck, Sandy
