Your experience is a virtual mirror of my own (minus the friends forcing me into an experience where I was made to get high) as I also dislike alcohol and freely admit this. Hell, I'd rather have a glass of chocolate milk than an alcopop or wine cooler.
I have been drunk before (once, alone at home, just to see what it felt like) and it was awful. Do not let anyone pressure you into drinking. You are not alone, I promise you. Frankly I didn't even drink until I was 21 and legally permitted to purchase the stuff, and since then I've averaged about one drink per year (I'm 30 right now) so you can see how little that occurs. And yes, the expense is batshit crazy, even if you're purchasing it from anywhere other than a bar.
People will look at you strangely. What I always tell them is, "You know, I've just never felt like torturing myself by drinking enough of something that tastes like skunk piss to get used to it. I guess I respected myself more than that."
You might be 'weird' by the standards of cultural social mores, but at least you're not immature or downright stupid which is more than you can say for the ones who are absolutely moronic about drinking and other vices.
Oh, and just for fun, watch this:
Aren't you glad you haven't fallen for this?
