My poor little DS!

The other day I found a crack on the hinge of my little DS.

(sorry for the terrible picture)
Is this serious?? And most importantly is it repairable?? Because I don't think I have enough money to buy a new DS! I don't know how it happened exactly but I do think it's because I've been falling asleep whilst I'm playing on it!
Please don't let it be serious!!
