I too used to suffer from very scary anxiety attacks. I didn't seek treatment but I don't recommend the same for you. I would however see several different health professionals for opinions as I've seen some people who were prescribed very powerful drugs that definitely made the problem worse in the long run; at the time they got relief but they ended up highly dependent upon these substances and had trouble conducting normal daily affairs. Good luck nakur, I'm right behind you on my 21st day.
