I used to be scared of elevators too -- back when I had agoraphobia and when I was in the recovery stages. I didn't like being "trapped" anywhere. I still feel kind of freaked out sometimes if I'm going up an escalator and there are people in front of me who are just standing there and not walking up the escalator. Sometimes that makes me feel trapped and I can feel myself starting to tense up and inside, I'm screaming, "WALK, WILL YA!" I was on a pretty steep one a couple of weeks ago and that happened. I was dizzy and shaking by the time I got to the top.
Thanks for letting me know I'm not alone.
