Hi. So I have acrophobia, which I didn't know until I went on a Go Ape Adventure Course. Over time this is gradually getting worse. It started with me not being able to go close to the edge when up high, then to feeling faint and dizzy up high bordering on having a panic attack. Now if I'm in a building that is high and I'm on the ground, I can't look up or I feel weak at the knees and feel panic setting in. 

Does anyone have any advice on how I can deal with this please? It's starting to affect my life now.
