I suspect you have Ovarian-Adrenal-Thyroid (OAT) Axis imbalance, with estrogen dominance (which could be blamed for your cervical cancer and hysterectomy).
You may also have multiple mineral and nutritional deficiencies, stemming from gut dysbiosis.
A food elimination diet would be in order.
Following a BRAT for a few (bananas, rice, apple sauce, toast) usually helps with diarrhea, but take some coconut water (not the one with added sugar) to keep you hydrated and mineralized.
Could you post a timeline of your medical history?
For the time being try taking probiotics-highest quality you can afford and ask you obgyn-if you have one- to
prescribe a bioidentical progesterone cream as a trial
If s/he's not open to this, seek a reputable Functional Medicine Doctor to help you with all your health issues.
Your high cholesterol is consistent with hypothyroidism and your iron deficiency is a known factor in low thyroid function.
What treatment did your doctor offer when you saw him/her 9 months ago?
Looking forward to your reply.
Best wishes,
Niko
