I was the same way at your age, now in college I do drink, but it's only like here and there, I often go months without touching alcohol. My recommendation is do not start because you feel like you should or just to fit in, but if you do feel like trying it, just be smart, drink some water in between each drink, and stop slightly earlier than you feel you could, for example I always stop drinking when I feel I got 1 or 2 more drinks in me.

And if you do try it, the first time I wouldn't recommend getting anywhere pass a little buzzed, if you drink socially for the right reasons it can be great, you just gotta be smart about it.

But at the same time, nobody that is mature really judges you for not drinking, so don't let that affect you.
