Can you explain more about it? in what condition it happens?
It occurs  when exposed to heights. It is also know an fear of falling

I see. Have you been attacked with it before? Because it may result in a panic attack.
I did not experience panic attack, but I try to avoid it, It makes me very uncomfortable
There are some severe cases where people may become unable to leave their homes. DO you experience this too? 
No, I am fine until it does not get too crowded, I still must go out if I have an emergency thing to do
like other phobias it is a  traumatic experience. I am sorry you have such
