Newly Diagnosed with Complex Hyperplasia with Atypia (EIN)

I am very scared and would love support from anyone who has gone through this. I have always had irregular periods - my cycles averaged around 40-50 days. About 22 years ago, I had a lot of bleeding and the gyn did a ultrasound and biopsy which came back fine. After that, all of my Pap smears came back normal and I have always been HPV negative. Two years ago, my general pap smear showed AGUS and atypical squamous cells, HPV negative. I had an ultrasound as well as biopsies of the endocervix , cervix and endometrium which all came back benign. Only the endometrium showed simple hyperplasia without atypia. In December, I had another pap smear which was clear of AGUS but showed atypical squamous cells of unknown significance and HPV negative. My doctor tried to do a biopsy in the office but it was too painful and we scheduled a D&C with anethesia instead. That was in late July and the results came back reading "Endometrial Polyp (Curettage): Endometriod Intraepithelial Neoplasia". My doctor called and said that they did not find cancer but that it still needs to be addressed, recommending a gyno-oncologist for a hysterectomy. I am 50 years old and have no issue with the surgery but I am terrified. I see the oncologist onthe 24th.

My husband went through BOT/throat cancer two years ago and I know that going through that is amplifying my anxiety. (He is doing great by the way!)
