Frankie you know what that makes so much sense, never thought of it that way before. It's just crazy how everything escalates from one fear to the next. For example I always had a mild fear of spiders for as long as I can remember and when all my other fears came that fear became 100 times worse. I have to try and stop my mind sometimes from worrying about other things as I fear it will just become another one of my fears.. if that makes sense. It's true the only way to beat it is through exposure.
One thing I have found that has helped me a bit by going on some buses outside of London and some cars is a 'life hammer' it can break through really thick windows and just gives me that extra bit of security in my mind.
