I'd say, sell back the games but make sure not to get store credit =P Then, go out, enjoy yourself - unless you're in the southern hemisphere, it's probably really nice, so go out for a walk, go swimming, etc. I'm ignoring my backlog for a while, since it's been gorgeous here after a kinda shitty winter - been slowly but surely getting into shape after a 1 and a half year long relationship where I kinda got lazy =P So now that I'm playing the field again, you have to look good, you know?
You can also try treating games as a social thing - if you have a few friends who like games, you can always play multiplayer games. Or take turns playing single player titles.
Oh yeah, one really important thing - don't feel you need to rush to buy everything people on here say is good. Find what genres you enjoy the most (I'm sure you've narrowed down your tastes this much ) and read up about the best games from them. I'm a lot happer now that I've narrowed myself down to playing games from 3 or 4 genres, instead of buying everything that gets an inordinate amount of hype on these forums.
Also, a lot of modern games require commitment, like 10 hours plus to make it through, so go back to the oldskool - 8/16 bit - the games are much shorter but offer even more fun than most modern games, where you're sitting through 1 hour tutorial levels or overwrought cinematics before you even start playing
