Drinking?

My friends (we're all between 16-17) are going to a party on Saturday which I was invited to but decided not to go because it would have literally consisted of drinking until 6am passing out for a few hours and then going home. I have drank before but to be honest this is a little trashy in my opinion. When I said I wasnt going one of my friends told me I needed to step out of my comfort zone. Am I being too uptight? My viewpoint is that getting wasted at this age is unnecessary and irresponsible but she made it out that I'm too much of a 'mom'
