You have "Derealisation". Go to this link and read about it. http://en.m.wikipedia.org/wiki/Derealization it's not actually a serious thing, just very annoying and upsetting. I had it for 5 years before it went away. The key is to ignore it. Worrying about the sensation fuels it.
Wow you're the first person I've found that feels that way and is somewhat associated with dysautonomia. I'll be praying for you and that they can figure it all out and find a cure to fix this
I also feel that way (have on and off for many years - my current episode also started oct 2013) and it is disturbing... for a long time I thought it was mental illness, have recently been diagnosed with CFS and I know some kind of dysautonomia is part of that (but still trying to figure it all out)
