On two occasions in the past year ive tried to be a hero of sorts, each time i got the crap kicked out of me.?

I don't know you, anything other than what I just read. I'm just more than twice your age and I'm proud of you even admire you. I do worry for your safety, of course violence is not the answer but protecting those of misfortune is the exception. 'Fire with fire', but be just as offensive as defensive your a smart kid, use it. Get to make model, tag number of the vehicle, I'm sure you know the bullies, turn them in- school, police parents. That does not show weakness, it's maturity and that's the 1st step to becoming a great man, not a punk. Go online and find how to defend your self, practice, you the bike boy and the girl, work with each other (SAFELY) don't carry any weapons or such. Your best weapon is knowledge, know the area you hangout / walk/ commute through. Stay strong, never give up.
