can anxiety cause this

i do have anxiety and i constantly feel lke lightheaded or like a bobble head
if im sitting on a chair i feel like im gonna fall off or i constantly have to keep moving my back up against the couch that im sitting in
i have had blood work and all is good and catscans all good
is it just anxiety

i love to play bingo and its gotten so bad that sometimes i sit on the floor
if i sit in a chair it feel like im on a boat rocking like im gonna fall off
was scared it was a seizure coming but DR said no way once again
and he seems to think it will go away once i get used to it
glad to hear im not alone
