Getting drunk. I don't get it

I've never understood what's supposed to be fun about getting drunk. What's fun about slurring and stumbling and acting like an idiot? Or, even worse, falling down, vomiting, and passing out?

I guess part of the problem for me, is that I just have no tolerance for alcohol. I'm completely drunk after 3 or 4 beers. And being drunk is uncomfortable or painful for me. My face gets almost painfully warm after just two beers, and then I start getting a really bad headache. I'm usually in too much pain to get any enjoyment from being drunk.

That doesn't stop me from getting drunk occasionally, usually when I'm depressed. Which is a bad idea, because pretty much every time I get drunk, I get depressed, whether I was depressed before I started or not. Pretty much every time I get drunk, I end up punching brick walls, or at least fighting the urge to punch things and freak out. Especially if I'm in a party situation where there's more than two or three people around. Because I can't handle the social interaction, and I get pissed off. Pissed off at myself for not being able to be social, and pissed off at the other people because they can, and pissed off at God for making me be this way. If there is a God. Pretty much the only time I believe in God is when I want to blame Him for something. Or, when I'm really depressed, to cry and beg him to make me better, to make whatever is wrong in my brain go away, so that I can live like a normal person.

Getting drunk is a sort of escapism. When someone's drunk and barely conscious, they wouldn't be able to think very clearly, temporarily forgetting their troubles. I can understand why some people don't like it, but at the same time it is obvious why other people do enjoy it. They don't enjoy being drunk per se, but rather prefer being drunk and forgetful than being sober and aware of problems and stresses in their lives.
