I suffered from it for about 6-7 years before I decided I couldn’t keep living with it. I tried benzo’s, beta blockers, psychologists, therapists, hypnotherapy, alcohol, and everything else. Exposure therapy is literally the only solution. Put yourself in the most panic invoking situations multiple times a day and don’t leave the situation under any circumstance. I went from being near agoraphobic to giving presentations at toastmasters and at work.
