Hi OP, so sorry to hear that you are going through a rough time. It seems like nobody understands right?

I don't really know the treatments that you are on. I was on Estradot patches 50mcg then 100mcg with Prometrium which is progesterone 100mg. I can identify with the anxiety/panic attacks and the shaky part of things. I believe I was on too high a dose of Estrogen. I have come off estradot patches for a week now to reset my body and the shaky part is much better. Still not 100%. I then stopped taking the progesterone too, since my recent ultrasound for my uterus comes back fine with the lining.
I felt dizzy and weird at times too eversince starting on HRT. Apparently progesterone can dull the mental side of things. The packaging of my Prometrium says 'this medicine may affect mental alertness and coordination'. I also wrote to the manufacturer who says that yes progesterone can cause dizzy spells so best take it at night. Yikes! Sometimes I feel that I am more clumsy now. I am shaky doing work and walking...
Maybe have to tweak your treatment a bit. Maybe go back to your prescriber? I hope you feel better soon.
