Sorry to hear you are struggling, as the other ladies have said, try one thing at once. Don’t try and reduce your medication at the same time as changing your hrt.
Take one step at a time, so you can see what’s happening?
Just a thought, you are on Estraderm, I’m sure I’ve read that they are quite big patches, have you thought of swapping to Estradot which are small and stick well.
For what it’s worth, I hated my antidepressant medication when I first started it, but I’ve come to realise that it works perfectly, only when my hormones are balanced.
