Yep, I've definitely had days like the one you described. Sometimes they stretch on for a week, or even a month. I've had times when everything I touch, be it academics, social life, career stuff, etc., seems to go poorly.
Just remember that you're bound to have some really great days to balance out the bad ones, so just get through your finals and things will improve. The game won't matter in the long run, and you'll survive finals. And even if finals don't go well (I'm not sure if this is college or high school), it won't be the end of the world, even if it feels like it right now.
But I think complaining is good. It gets out emotion and makes it easier to tackle the things ahead.
