How can I recover iPhoto?

I was looking on iPhoto at some recent photos I took and decided to edit ("adjust") a few- I'm in full screen mode and my Macbook pro freezes. I can't get out of the program, it's not moving, and the esc button isn't working, so I just shut my computer down. Well crap, when I turn it on it has erased my iPhoto library entirely. All 3000 some photos since I've had this computer for Christmas. What the heck? I tried downloading some recovery programs, and doing the "control+command" and open it and have it "rebuild" thing... I'm just mostly lost and would love ANY help with recovering these pictures!
