I am a victim of sexual abuse, but I am here illegally, I heard I could get my papers because of my situation. Is that true?

You may be able to seek a U visa. More specific details are needed about the crime perpetrated against you as well as your cooperation with the authorities. I would encourage you to speak to an attorney directly. You can read more about U visas at http://myattorneyusa.com/u-nonimmigrant-status-u-visa.
