This is what worked for me. You have to get fed up with it enough to where you don't care what it does to you. You have to say, "come on, do your worst" and mean it. Then, the feelings start to retreat. It seems weird, but it feeds off fear, and when you DEMAND the worst panic attack, it has nowhere to go. Then, slowly, you keep this up, day after day, living your life without regard for how you will feel. Then, in about a year and a half or two I was taking a trip to Disney world for a full week and rode everything! It's the only thing that worked for me, and I tried everything!
