Hi OP
Could I suggest you spend time studying your condition and the solutions available to you more than the benefits, the benefits will be a tricky one to navigate but fingers crossed you can get something.
Only reason I'm posting is that some of your endometriosis cures are NHS bullshit that GPs are telling you - a hysterectomy will not cure your endometriosis, but yes it will stop the bleeding and adenomyosis.
But so will the mini pill or the coil.
Please don't let them inject you with zoledex or any other drug to put you into menopause, to stop bleeding the side effect are bloody horrendous, and they should not be using this as a "cure" even short term there are risks with bone density issues. Read more before agreement to anything like this.
The gold standard for you endometriosis surgery is wide excision surgery, read about this vs ablation. Essentially ablation is like laser treatment and wide excision is getting the endometriosis out at its root. You really don't want ablation, you'll be in and out of surgery's for years, you can wait and insist on a wide excision specialist.
So minor things you can do to help in the short term are taking antihistamines, low inflammatory diet and exercise. (Just walking helps) I do understand the pain and how crippling this disease is.
Good luck with future babies! It is possible at your age I did manage to conceive my 2nd even with extensive endometriosis.
