Oh yes i feel like that after my sunday outing every week, everything is disconnected from me, like it is a sort of dream, an out of body experiance. yes i know, Hang in their it will pass.
it is just your mind protecting it's self. once the threat is gone, you will start to come good.
I have heard of a beef snag, a chicken snag but not a snag, Sesitive New Age Guy, really...........hmmmm i suppose that is me 
OMG Karen, I can't believe it!!!!, i was literally jumping around the room when i read your message, mum came running in thinking something was wrong, like i had won the lotto or something.
Karen, do you realise what you have done?!!!!! this is a major step in your recovery Karen, i am still in shock, i can't believe it, i bet it was so hard walking in that front door, and yes i do know the feeling, sometimes when i go to town, i get to the point of almost passing out i hold my breath for so long.
I know the anxiety is bad, it is probably really bad, but you know what, the more you go the less the anxiety will have hold of you, OMg saying i am proud of you just does not give justice to what i am feeling, i bet you look beautiful, now you have a haircut to match your wonderful beautiful soul.
Karen, i know deep down you must feel a little proud of yourself for taking such a big step, i know it was not easy, if it where me i would be panicing for hours on whether or not to go. i would actually be pacing around the house.
sorry Karen i can't get the words out quick enough, my mind is racing so fast with this exciting news, i must give you a present for the good work.
Good work Karen!!!!!
