It is totally shit, endo is horrific and you do have to fight for diagnosis and the "treatment" is stuffing your body full of hormones. I underwent a chemical menopause in my late 20s to give my body a break from endo.
Why do they still call them "chocolate cysts" why don't they say blood filled? Stop giving it a cute name, they fucking hurt.
I was lucky, I was diagnosed over 20 years ago, managed to conceive 2 children naturally against all the odds and could afford to give up work which was the life changing bit. Endo is made worse by stress, the more stress you can remove from your life the better. I still have chronic fatigue due to my immune system constantly trying to remove the endo deposits.
It is sad she sees no alternative than the hysterectomy but treatment is just management, there is no cure.
