Is this bad for a 14 year old girl?

There was a jug of pink juice in the fridge, and I was really thirsty since my parents were out getting a jug of water, juice and milk considering we hadn't been home for 2 week from being on vacation. I was extremly thirsty, seeing as I couldn't drink like the bath water since it's full of bacteria out here. I started to drink the pink stuff but only took a few sips there and there. after about 1 hour and a half to 2 hours I've drinked half a cup. I just found a case of g fruit bricardi freezers that were empty in the recycling. Now I know what they are. I'm a 80 pound 4 foot 9 14 year old whose never drinken alcohal before. If it matters, I havn't vommited since I was 3. I'm scared. Am I drunk? I'm a girl btw.
