Again with the excuses. I don't care what kind of comment you can pull out, that's not how it works. If you go into a situation with a "this is going to suck" attitude, it will suck. If you try not to have fun (and don't give me this "i tried to socialize" bs, at that point your mind was already dead-set on not having fun), you will not have fun.
And if you're tired and incapable of moving, why the hell would you go to a place that's very energy-draining (unless you're extroverted, but I can safely assume you're not). Same for not being able to move, that's just a show of insecurity and uncomfortableness. NOT party mentality. You need to loosen up.
If you were physically not well, then you deciding to go to a party is like a marathon runner with a broken leg deciding to participate in a race.
