Have you had your thyroid checked - all the symptoms you mention are associated with low thyroid function? Even if you decide to have the hysterectomy, you should consider this. Please make sure that along with TSH, that the doctor tests your FREE T3 and FREE T4 (they MUST measure the Free values as that's what's bioavailable). Also, they should really consider testing all your hormones as you are reaching the age where many are declining and bio-identical hormone replacement can make a world of difference to your overall wellbeing. You can actually get all your hormones tested without a doctor:
Saliva tests: www.canaryclub.org (you do these tests at home)
Blood tests: www. healthcheckusa.com (they send you a lab slip for Labcorp)
You might also consider getting a second opinion. Dr. Margaret Christensen is a top GYN in our area:

She had one of the top OB/GYN practices in Dallas for quite a few years then had some health issues herself. She went back and trained as a functional medicine doctor and now is a very outspoken proponent of not taking the "cut it out" or "drug it up" approach to treating health problems that is so prevalent in conventional medicine (just as you are experiencing - i.e., if drugs don't work, then you cut out the problem organ), in particular for women's health issues.
