I am 14 and i feel nothing (Help)

I am 14 years old, and today i had a party with a bunch of friends. I am 175cm and weight ~60kg. I go to the gym most days.

So today i drank about 9 beers, spanning over the whole day, and a bit of “DIY” vodka drink. I didn’t eat much, but while my friends were stumbling around acting crazy, having drunken around the same amount and being substantially larger than me, i felt nothing.

What could cause this? If i remember, I’ll update tomorrow if i get a hangover
