There's no good path for you. There is no amnesty law for illegal immigrants, and is not likely to be one in the imminent future. The Dream Act (to give a chance of citizenship to people who were brought into the U.S. illegally as children) may pass if we get a Democratic President in the White House, although that will probably also require the changing of a few senate seats into Democratic hands.

Leaving the U.S. is a poor option, as you will be subject to a period of ineligibility to reenter the United States, from what you say a ten year period. You can discuss that, and the possibility of getting a waiver, with an immigration lawyer.
