What do you do when someone breaks up with you?

I feel so lost right now. My boyfriend broke up with me and I don't know what to do. I just want to get my mind off it because it's driving me crazy. I feel even more depressed now than ever before.

He took down the picture of us on Facebook and put up a nice picture of him. I deleted my Facebook after that because it was just too painful.
