I'm bloody tired... Peri menopause, or Chemo fatigue nearly two years post treatments!

I had TC as well. It put me into menopause. I am always tired, and still sometimes get slammed by fatigue. No one seems to be able to tell me if it's menopause, permanent side effects of treatment, or side effects of the medication (Letrozole and assorted others). I hope it's the medication. I realise slowing down is a part of getting older but I didn't realise permanently feeling exhausted was the deal. Surely it's not she said hopefully...
