Slumping.... Aaarrrrgh

For the last few weeks I've felt my chess game improve rapidly and feel that I've become a relatively solid player.  That is, I can beat the average person with little to no problems.  However, the last day or two I've been slumping hard, making silly mistakes, and generally not playing like myself.  I know exam time is coming up and I am feeling the stress a bit; but, is that a viable excuse?  Perhaps I have been practicing to much?  My plans perhaps have become to grandiose, and I'm not engaging within the simple game?

Any ideas? Suggestions?  How does one break a slump?

stop making bad moves :)

when i hit a slump I just keep playing. I dont play to win I just play to play.
