I am very claustrophobic and after my last trip to Disney, I ended up seeing a therapist because it reared it's ugly head so badly. Here are the rides I had most issues with, in order from worst to just kind of bad.
MISSION SPACE: no way on God's green earth would I even go near it..no way, no how!
RNR: I actually sat down in the car, pulled down the harness and started to panic. after screaming" I can't do this, let me out!" I had to use the chicken exit.
TOT: I was ok. I even made it through the preshow scary room. Until I was sitting on the ride and the elevator doors shut. Then I had to breathe my way through it, BUT I was glad that I went. It was totally worth it and I carry a small misting fan with me now so I think if we did get stuck I would be ok. Actually, I can't wait to go on it again. I will also carry a flashlight in case we get stuck, because it can get pretty dark on that ride.
SPACESHIP EARTH: At the top of the ride when you start going down backwards, you can actually see the outline of the triangles at the top of the globe. That freaked me out. I felt like the globe was closing in on me and I had to use my fan!
HAUNTED MANSION: The stretching room was hard for me.I held on to my husband the entire time and looked up at the ceiling. seeing all that room was a big help. also, I was in the back left side of the room, right where the door to the ride opens up. It helped to know that somehow.
SPACE MOUNTAIN: I was actually ok on this ride. I did feel a little cramped going up the first hill but it went so fast after that I didn't have time to get to freaked out. I have found that if my shoulders and arms are free, I'm ok.
RIDE IN NORWAY: I can't remember the name of the ride, but he room that they hold you in right before the movie made me a little nervous. I ran through the movie room and out into the gift shop!
COP: I was ok because there weren't tons of people in the room, but I can see how I could have freaked if the room was packed.
On the buses, I stay in the front or right by an emergency exit....same with the monorail. Oh, and the little misting fan was a life saver for me. When I panic, I get hot. The then just spirals downward. Having the fan helped me keep my "cool" in more ways than one.
My therapist said to take a deep breath and hold it for ten seconds. Keep repeating until you are out of the situation. Apparently it helps to slow the "fight or flight" reactions triggered by fear.
I can't think of anything else that bothered me right now. Hope that helps and please know that you are not alone!!!!
