not sure if this helps you or not, but i’ve been on atenolol for a few years now. it’s a beta blocker. lowers blood pressure and mitigates anxiety attacks. which are different from full blown panic attacks. i’ve found after many years of darting out of restaurants, church, and other social activities, that the beta blocker helps alot. same day results. but having said that. you still need to work on the trust. i can still have panic attacks without anxiety attacks. but the panic attacks are now controllable with the correct mindset. i’m not down and out shivering in fear for the next several hours plus the next few days of depression. more like five minutes of “let’s pull this shit together”. that feeling of when “someone scares the f**k out of you as joke” but noones actually there, is completely gone. again it goes back to dealing with the underlying causes. therapists can only do so much. what really helped me for the fight or flight response, which for me changes to different physical experiences each time you have a big one, is realizing that I don’t control what I truly want/believe I control. I needed to adopt patience, go with the flow. and finally love myself, whether or not myself need some adjustments here and there. commit to yourself first. make your own expectations. if that falls short of others, too effin bad.
