Raindancer, racjen makes a good point about testosterone. I added this into my HRT regime in January. Although my anxiety was mainly a morning thing, and nothing like as severe as that of some members, it has gone completely now. I have also found it good for improving stamina (the main reason I asked for it), muscle strength and libido. However, I don't know how amenable GPs are in prescribing testosterone. Mine was prescribed at an NHS menopause clinic, but you could always ask.
Anyway, I do hope you feel better soon, whatever you decide to do. You have been through a lot recently.
