I'm the OP and I'm so glad you all have chimed in recently!! I haven't been on the disboards as much lately and I didn't even realize the thread became "active" again!
I don't have panic attacks as much as I used to (maybe 1-3 a year now). Surprisingly, the latest one I had was last year when we went to Disney's Hilton Head Resort. Me and my daughter were riding bicycles from the beach, back to the resort, and we took a detour, seemingly lost, and mixed with the heat, I really thought I was gonna lose it!! I got really scared, but my daughter handled it very well!! Getting me back to the room, drinking lots of water, and cooling off and resting, and slow breathing. Then I was fine and we had a wonderful trip!
I've gotten better over the years with the rides at WDW. It took a few years, but finally rode a few things I was really afraid of. But still, I can NOT do Tower of Terror, Rock N Rollercoaster, or Mission Space!
