I am so sorry you have such an awful phobia. I hope you get some good replies here, all I can do is wish you the best and know that I am thinking of you today. Phobia isn't one of my issues, though, anxiety is and I'm on Pexeva, a different brand (company) of Paxil. It really seems to help me. You are in the right direction of looking for a therapist who specializes in phobia, panic attact and unless you are referred to one or they 'advertise' that that is a specality, I don't know how you would find one.
Good luck, and don't give up looking uintil you find the right T.
