I have terrible claustrophobia and have for as long as I can remember. I am taking a trip soon which will involve situations that terrify me, including being on a plane and going in lifts. Unfortunately I can't easily get out of it without consequences. I wonder, can anyone recommend me any good books about claustrophobia that might help me to deal with it? Something I can download onto my kindle or phone and read while travelling would be great. I would be so grateful.
