Hi had exactly the same and referred to gynaecology. I had a polyp, benign and removed by hysteroscopy, gives a clearer picture of what is happening in the womb. Gynaecologist told me to come off HRT. I have struggled since I was 50, now 59 on and off HRT. Sleepless nights, anxiety. I have found that even when tired going to the gym helps, pilates, yoga etc. It's good to talk and we are not alone. I seriously thought I was going off my head. I am cold turkey no HRT so take magnesium glycerinate, Vitamin D and a Well Woman Vitamin. Soya, collagen anything that has been recommended. When I came off HRT I had trembling and found this can be common on Balance Me site. I hope you get resolved and you are not alone.
