I got pantsed. Boys saw me naked?

I was talking to some boys out of class. We were planning on going to a movie later. But I didn't know they were planning to pants me! So while I was talking to them a guy came from behind and pulled my shirt over my head. I couldn't do anything! One guy detached my bra while the other pantsed me! He took my thong down to! I was still unable to move. While crying I tried to put my clothes back on until I realized the guy took my shoes, thong, and pants. Everyone in school saw me naked! Guys started to touch me! Help please!
