Skrillex concert questions?

My sister, her boyfriend and I got tickets to the Skrillex concert on July 12th at The Pageant. I'm a really big fan of him, and I'm super excited to go to his concert. Wellllll, problem is, I'm 12, turning 13 in September. And I'm pretty sure that the people at his concerts are tripping out on drugs. I know the mosh pit can be a really crazy place, but I know he stage dives and oh my god, I WANT to be down there if he does. But believe me, I'm a pretty mature person (not trying to sound self conceited haha). I really want to enjoy this concert, but I don't know if it's a good idea. Though I'm totally up for the craziness, I love crowds, and moshing. Most would say I'm way too young to go to his concert, but what's your opinion? I got the General Admission tickets, meaning I can sit in the seats (seats are first come first serve), or I can go in the mosh pit. I already know about the minor surcharge and all that stuff. No rude answers or comments please.
