I too have severe anxiety, probably inherited from both parents. The only thing that’s worked for me is Xanax. Ssri’s also did not work for me, just made me nervous.
Right now, benzos are the current “villain” drug, and I’ve encountered places that wouldn’t write them. I’m lucky to have a pcp who is willing to prescribe it. If your current Dr won’t, find one who will.
I’ve taken Xanax as needed many years, and I don’t seem to have cognitive issues at 71.
