Lisa; I have panicked and froze crying before a 30 foot drop before. It's hard for me to jump off the 3ft diving board at the pool. I get nervous being an extra 1-2 feet off the ground. I think mine's a little bit intense.

I don't have many fears but this is a hardcore phobia and fills me with sheer terror.
I've been trying to work on it... But little progress has been made. It takes a lot of will power for me to do things like go on ferris wheels.
Oddly OK with roller coasters, however I am terrified during the first 10-20 seconds going up that hill.
