My guess is that part of the problem is that the hormone system as a whole is complex and the individual hormones all affect each other. Cortisol, sex hormones, insulin etc all interact.
Medicine today takes a single simplistic approach - low Oestogen,=add more, use dose that works for the average woman, use cheapest option etc. But it does not look at the system as a whole to work out if that Oestrogen might affect something else and what the knock on effect is on other hormones or how the rest of the endocrine system is working.
Also it does not try to work out what the right dose of each component is for an individual. The result can be an unbalanced system that only works for some women and can cause over/ undertreatment.
Hopefully over time the sophistication will increase until more people can get the right hormone treatment for them individually.
We are not there yet, so as the OP said, the treatment is not right for her. It goes without saying, everyone should follow the right approach for themselves regardless of what others do/ think. There is no other way of judging who it will work for in advance or knowing why it is not right for her, yet....
I am not sure HRT itself is the problem, rather it is how it is used at the moment. I am fairly convinced that the it would help most people's health over the long term if they could get the right treatment for them individually. I think it is this prospect that leads people to persist with HRT when it does not suit them or encourage others to do so. It also means some of us spend a lot of time, money and effort trying to improve the situation for ourselves.
Hopefully it will come for future generations but until then only you can tell what is right for you.
