What can happen to a 16 year old who got caught drinking underage?

Hi, last night was a bad night. My 19 year old boyfriend had his 21 year old friend buy alcohol for us. Our other 21 year old friend and his 18 year old sister were there too. & we were getting totally S*** faced. Well, it all got out of hand. I'm like the shyest person ever, but I started dancing and kissing his sister (which I've never ever kissed another girl before) & I was like projectile vomiting into my garbage can, but I kept drinking cuz I felt better. Idk, I guess this is TMI, but anyway the cops came cuz of a noise complaint or something and my stupid mom opened the door sooo they came upstairs and saw all the alcohol cuz it was just laying everywhere & they breathalyzed us. I was at 1.04 and my boyfriend who was drinking too managed to get .00. Idk, what's gonna happen to me? Like will they make it so I don't get my license for a few years? What else could happen? & please don't go off on me about how stupid it is to drink underage and stuff, cuz I know. I'm usually a very good kid who doesn't do those kinds of things, but last night just got too out of hand. & I told my boyfriend that I never wanted to drink again, cuz I don't like not having total control of what I'm doing & he said he didn't want to drink either. Soo yeah. Please help. Thank you. Oh, & I live in PA if there's different laws for different states.
