I cannot say, but acrophobia is described for those who are not really high up.
Acrophobia for me is either not wanting to fall or being really high up, so I hate unsturdy ladders and i height sturdy airplanes
I'm not that afraid of heights, but so many people in my family are. I see. Acrophobia is described as having extreme fear of heights. How high up do you have to be to start hating it?
Acrophobia is an extreme or irrational fear or phobia of heights, especially when one is not particularly high up.
