Help!!! I'm scared of growing up!!?

So i'm 13, turning 14 in the summer, and I'm scared of growing up!! I feel like such a little kid compared to most people I know!!! Like half of them are pot heads, some sneak out of their houses to hang out with friends at like 3 in the morning, most get drunk like every weekend, some girls I know have given guys blow jobs and have gotten fingured, and most guys have gotten blow jobs!! The worst thing I've done is get home like 20 minutes late from hanging out with friends!!! Like most of the people (and we are only in grade 8) think that getting drunk is no big deal, and when they find out somebody has never gotten drunk (like me) they would make a huge deal out of it!! Some guys today were bragging about something that happened during the weekend, saying that they all snuck out at like 2 in the morning to hang out and invited 3 grade 9 girls. Well, 2 of those girls snuck out some vodka and shot glasses from their parents and all but 2 of the kids got drunk (the other 2 only had 2 shots they say) and this kid (he's 12!!) and one of the girls locked themselves in one of the bedrooms, and the guy fingered the girl and the girl gave the guy a ********!! And today one guy in my class came to school after lunch drunk!!!! And my best friend, her boyfriend is a drug dealer and does weed and so does she. So I feel like a little 5 year old kid compared to everyone else, and now I'm scared of growing up if it means doing all that stuff......plus I'm going to high school next year and this makes me even more scared!!! Please help me!!
