I too used to have fear of enclosed spaces, and still do a little, but have gotten much better since taking anti-depressants etc. I used to hate flying, because as soon as they locked the door, I felt trapped. I guess it is a common feeling for people like us, judging from the amount of correspondence you've had. I also hate those automatic car door locks, that lock up when the car reaches a certain speed. I feel locked in, and fear not being able to get out in case of emergency. I guess that is foolish, because I could just unlock the door in case of emergency. So it is just a feeling, and probably has something to do with our brain chemistry. I believe I was born that way, because, I was told by my parents, that when they used to try to put me in a bunting bag; a zippered coat bag for babies, I used to freak out then too. Isn't that interesting?
