Don't get upset, it happens. You'll learn gradually. And if you don't learn, it's not a problem either, you can't do anything, some people close their eyes and that's it. Fear overcomes almost everything and with the cover of the eyes do not cope quite a lot. As a last resort, pass into judo, maybe there will come out more luck, and as self-defense from street hooligans, it is even more effective will be. But even if none of the sports will work you do not upset especially, because the status of men is determined by his actions in life, not the ability to fight on the streets.
