Hi WLL and welcome!
I am sorry to hear about
your Rx losing its efficacy.;(
You could consider trying another SSRI/SNRI...as you may react positively this go around...
...or perhaps you could ask your doctor about
another classificaion of meds such as an
aminokeytone A/D as in Bupropion or Wellbutrin...or a
beta blocker, or even an
antishistamine prescribed off label for anxiety.
For now, (and long term use actually!) until you get your Rx resolved, we have some awesome Resources to check out here:

Take a look and see what tools you can pick up to manage your anxiety while you are in transition and beyond.:)
Wishing you the best, and inviting you to post with us anytime for anxiety support!
