The same thing happened to me, and so I was diagnosed with GAD and OCD at 47, then went on to take antidepressants.
Prior to that, sure I'd get stressed, but absolutely nothing like how it's been since my late 40's. It's no coincidence that many mid-life women take antidepressants.
HRT can help, but only the right combo. I'd love to be of more help but don't know how, sorry 
Oh, I am sorry to hear that because I know it well how desperate it is.
For how long are you on antidepressants? or did you quit them?
I tried profesterone, estrogen … with bad side effects…
Well, I continued on various different ones up until I was diagnosed with low sodium at 60, so it was unsafe to continue. Nevertheless, having no help for the anxiety, I took tiny (2mg or so) doses on an as-needed basis when I needed to, plus CBD gummies and sometimes Benadryl as CBD gives me histamine issues.
In total about 13 years on antidepressants but they don't do a thing for me now, it's more of a case of adverse reactions. So they kind of quit me, rather than the other way around

Sorry to hear you had side effects from oestrogen and progesterone. I get some too, so have to take breaks from the patches to let the build-up out.
There is help out there for your anxiety, maybe you could try a different kind of HRT? Lots of us cannot take utrogestan. Or would you be prepared to try antidepressants? They help millions of us. No need to suffer more than we need to.
