Boys at School Made me drink 5 Big Bottles of Coke and I wet my self. HELP?

I'm a Boy and at High school today these boys came up to me with 5 big bottles of and said if you don't drink all these in 10 minutes we will punch you in the face. So I did as I was told and began to drink the bottles. Each time I drunk a Bottle a big gush of urine would come out and I would wet my self badly. I managed to do it in time but I felt sick afterwords and my trousers were soaked. The urine went down into my shoes and socks, and I stunk. What should I do?
