Think of it this way: at least you're calling it quits early in your playground career, rather than dragging out the humiliation likeZOIDBERGme... *sobs*
Don't worry, though, in all honesty. I've been making screw ups and idiotic posts for two years, and even though the hostility is positively dripping off of a few people, there's always gonna be a bunch more cool people. I reccomend maybe giving FB a break for a few days, weeks even, before making a decision.
