Managing after a bad beat?

[McDirk]

Hey all, I was playing on Bodog 50NL earlier this evening and lost 3 full buy-ins in 30 minutes on three separate hands. On the first two I went all-in on the turn and lost to a three- and then a five-outer, and just when I had built my stack back up to $80 I pushed all-in preflop with aces and lost it all when some guy with $300 mysteriously called with T-8o and hit two pair at the river. I've heard that as one improves at poker one will start to lose to more and more bad beats simply because one usually has the best hand more often, but I'm actually dizzy right now. How do you all handle this?
