Answer 1

Yes it’s phycological. I’ve got a scaffolding friend who seems to have no fever of heights (he’s worked on some of the largest builds in the world and specialist in scaffolding that hangs under buildings? Do t know the word only seen the pics)
Now if I try walk along a 9 inch wall 12 feet up my mind is telling me this is dangerous and I get a cease and desist order from the brain after all it’s trying to protect me!
My friend has broke that fear and can freely walk do some mad things

Answer 2

Vertigo, aka height intolerance, and other terms.
