I have acrophobia (fear of heights). Earlier at work (storage) I had to go the 2nd floor of the building to open a small fence so that another guy can bring down some stuff with a truck. With the fence opened, one can walk down and fall. I opened it, looked down and that feeling has completely overcome me, I backed down and grabbed something to feel safe...and it was only 4 meters high. I always had problems with heights but now I'm really sick of it and I'm not sure how to fight it.
Are there any good advices to kill this fear? But I admit, having acrophobia sure does a damn good job keeping me safe from falling from anywhere. It is also a good thing...
