hi there castleinthesky,yes iv had this feeling, i could not go out of my house alone for four years if i did i would feel dizzy sick and like i would faint,its called fear and if you let fear win you wont get better,i learnt this from the linden method, one day after listening to tapes from the linden method i gave it a try(i took my phone with me in case)i walk to the local shop and back by myself and i felt really bad but i did it ,it was the worst feeling ever,i just kept telling myself "i will not let fear win" .it works good luck xxx
