Hey Matt.
I feel that way too. But its because I have vertigo from a damged bone in my ear (made worse atm by my meds). If I look up, I swear Im spinning. My head feels it and so does my body. It causes great anxiety. It is a very uncomfortable feeling. Sometimes, I think Im moving when Im not. Idk, if that helps. But what you are discribing sounds exactly what I experience with this vertigo. I hope it helps alleviate your anxiety somewhat
