Replying to What should I do

I'll keep it short these hardcore skid gangster kids want to beat me up for no reason and they think I snitched on them when I told the principle I'm not snitching on anyone after he asked me what happened. the kid got cot because he hit me in front of a camera.
And heres the long story
It started out when after fot this one kid for having long hair, and I was just chilling at the smoke pit and they come out and start bugging his sister, who flips out at them and. So I'm just watching this happen with everyone else and the guy looks at me and says why you smiling, I ask are you talking to me or the guy behind me " who they are mad at for sticking up for the long hair kid"  Or was he talking to me. He said yeah you, so I said I'm not and just mind my own business like I was. After everyone pretty much left they said come over here, I didn't think they had beef with me and just wanted to say something. he walks up to me and shoulders me and I get winded, so I'm wondering what the fuck I dont even know this kids name. This guy is around 17 18 or so and if I tried anything back everyone would jump on me. so I just left. now this kid thinks I snitched on him and the office wouldn't leave the matter alone, after I said it's just going to make it worse, and the principle just said I'm going to find out anyway.


so what should I do, press charges, change schools?
