I used to suffer extreme anxiety/panic attacks so I know how awful it is. I finally said "F**k" it! "I can just die! I don't care" and ironically they just stopped. Benzo's help but Doc's hste scripting for them these days. Maybe a glass of wine? Hope t his resolves soon. Remember, the worst that can happen is to pass out from hyperventilation which is rare. I wish you my very best.
