If you're able to afford the payments, and are otherwise financially stable, I'm not entirely sure how another 5-6 years will worsen things.

Unless the economy manages to crash again in that time, and worse. Then, though, you'd probably be in a crappy situation even if you left now.

More than likely, at this point, your house will be worth more (though probably not a lot more) than it does now, and (since you've been meeting your payments) your debt will have shrunk, too.
