Dont feel safe and im scared of people!!?

ok, when i am walking down the road i feel like someone is going to beat me up. i got punched in the face by this guy last year for walking on the pavement (i think he was high) and he is known for being viciouse and he told my friend if he gets in his way again he will break his neck. and im scared ill run into him again and he wil do the same thing again. i sleep with a golf club, hockey stick and a bush knife. but im scared of public. whats wrong with me????
