Justified reason for stealing at school?

hello I am a freshman at a small charter school who recently had a expensive pair of football cleats stolen.angered by that situation, I entered school today with a kind of vengeance thinking that if I stole someone else's stuff that it would make things right.the stolen items were a pair of headphones that cost around $80. I was later snitched out by the same person who told me about the headphones and now I was confronted by the owner and his posse. He was cool about it but things quickly escalated when I initially deny having any involvement. For some reason I thought that showing them my backpack would be OK because I believed the headphones were obscured from view.a big scene quickly Amherst and it ended with the kids shouting Mexican curse words and calling me a thief in front of everybody. I was called up to the office, where I opted 2apologize to the Kid. we supposedly squashed our beef but I feel terrible gilt, as well as being worried about being labled a thief now from everybody. I've had so much s***stolen from me over the years and I was sick and tired of it. What can I do to hold my head up high and forget about this?any help would be greatly appreciated thank you very much
