My doctor had me make of list of my thoughts during an attack. Some of these things were: Losing control, Using the bathroom on myself, Choking and Passing out. After I made the list (it was pretty long), he asked me how many times any of those things actually happened. The answer was "Zero."
He then had me make a list that said stuff like:
I am not going to lose control.
I am not going to pass out.
I am not going to soil myself.
I am not going to choke.
etc., etc., etc.
I kept this list with me and he told me that if I felt an attack coming or if I did have an attack, to read the lists repeatedly. Out loud if necessary. It felt kind of silly but I did it and it started to help. Not only was I verbally for to re-direct my thoughts, I was also distracted (by reading) instead of concentrating on the attack.
There were times when I was so frustrated that I would just burst out into tears. I found out that crying is a great stress reliever, especially during an attack. There were times that I actually made myself cry just so I could feel better.
Different things work for different people but the main thing is going to be CHANGING YOUR THOUGHT PATTERN. THis can only come from YOU. You didn't get like this overnight, so its not going to go away overnight, but it can be overcome. You just have to take each day as it comes and deal with each incident as it comes. Once that incident is over with, try not to focus on it. Remind yourself that you got thru it, you didn't have a heart attack, you didn't stop breathing and that you are going to be fine. Then go find something else to do that keeps your mind occuppied.
