I used to be into loads of different extreme sports. I still am to a degree but I dont get the fun out of them I used to. It varies massively day to day but I often cant tell the difference between frightened or excited and consequently what used to excite me now freaks me out. Will I ever get my nerve back? Its really frustrating and holding me back. I dont want to give in but as my level in the sports increases I'm at more and more danger so I back off all the time. If I've had a bad night with nightmares etc then my threshold is much less. It has got better as going to gym used to trigger the same feelings. Its adrenaline overload but it my head doesn't seem to know what's going on, if its fun or a threat.
