Hi. I'm sorry to hear that you are feeling this way. Have you done a google search on "depersonalization / derealization?" I guess a lot of people with anxiety suffer with this and it sounds like what you are describing and if it is it is very normal for anxiety sufferers. I do hope you feel better.
