annie I suffered from severe claustrophobia for over 40 years. Panic attacks, the works. Even the thought of being in a confined space could being on a panic attack to the point of nausea, heart pounding, sweating and fainting. 40 years, no lifts, no trains, no planes, no backseat of cars, no rooms with locks. Unable to use a toilet away from home as I couldn’t shut the door.
I worked at it, one small step at a time. It took time.
I can now go in a lift and cope. I have been on the underground ...in a tube train ?. It can be done annie. Don’t give up hope. Just one small step at a time x
