Re: Weird Symptoms...almost unexplainable.
That feeling that you have is what I have been going through for a long time. It is much better now but still not where I want to be. Depersonalization is what my Dr called it. When I get this feeling, which is most of the day, I try to focus on a specific item in the room and look at the details; ie: color, texture, etc. and at the same time I put my hand on my belly and focus in on my breathing. This calms me down for the moment.
No one does well when they don't get the proper sleep. I think that people with anxiety is probebly worse when tired. I don't sleep well and It puts me in that depersonalization state.
Klonopin has helped me - but CBT and the book Hope and Help for your Nerves I keep with me at all times. Have you heard of this book?
Anxiety can bring on all sorts of sensations through your body - try to stay calm and make sure you are breathing the correct way.
