Charley if you ever do figure all this out do let us know the answer.
It can feel like you are going mad at times. I often used to think to myself the only consistency is it seems totally inconsistent.😲. It's taken me some time with lots of huge ups and downs, but I think I am now on the oestrogen and progesterone hrt regime that suits my needs right now. It's not perfect but I was never expecting a cure, just more stability. It can be very much trial and error and patience, which is the worse thing to try to be when your hormones are playing up - tbh I never thought I would get as stable as I am right now. So I wish you well, and just post any question any time, or sometimes what helps me more than anything is the huge support when so need it most
