@Middicat I'm going to offer you another opinion (and I'm w health writer, having written for Patient and other similar sites.)
I understand your feelings but there is another side to it and some of your concerns are based on out of date info about treatments.
Hysterectomies are not without risk- it's a major op and can- worst case- leave women with other issues, albeit rarely.
Your periods are likely to stop soon as you are 54.
I can't think of any 'kind' way to say this (sorry!) but you are assuming certain treatments won't help based on other experiences, but that doesn't mean a new treatment won't work!
I mean the Mirena. You assume it will make you depressed but unless you try it, you won't know. And assuming it will make you depressed is a pretty sure way of assuring it will, because that's how our mind s work.
The progesterone in the Mirena is not the same as Provera. It's like comparing apples and oranges.
Likewise the copper coil is known to cause heavier periods so you can't compare the Mirena with that.
Would also add with hormonal imbalance (too much Oestrogen) which causes lining to thickness (without Progesterone lost through menopause) I am seriously moody and get cross very easily and don't want that to go on forever either.
It's not too much estogen that is causing your moods- estrogen improves mood which is why women are prescribed HRT. If you have a hysterectomy, they may or may not remove your ovaries. If they do, you would be plunged into surgical menopause and may find that 100 times worse than you are now, with hot flushes, low mood, night sweats etc, and would need estrogen replacement to help. You wouldn't bleed (no womb).
You can't make a dr give you an operation, even if you pay for it- that's not how it works. Any dr who does on op 'on demand' without trying all other non-surgical options first is not working ethically.
I can see how when your periods are likely to stop within a year or so, your drs are holding fire, want to try the Mirena and also see how that goes.
One thing worth mentioning is that a woman's weight affects how much estrogen we produce (women who are overweight post menopause still produce some and puts them at higher risk for female cancers.)
Weight is a high risk factor for endometrial cancer, both before and after menopause. Not saying this applies to you but it's worth being aware of it.
Maybe give the Mirena a try for 3-4 months, with an open mind, not expecting the worst (!) and then see how you are.
Good luck- I know it must be debilitating.
