Many more details are needed. Are you parents here and if yes, are they in legal status? Do you have any children who are U.S. Citizens? Are you married? Which country are you from? Did your family apply for (or had a petition filed on their behalf) prior to April 30, 2001?
You should consult with an experienced immigration attorney and have knowledge about your entire immigration history and that of your family when you go to the appointment. There may be options, but a much more detailed discussion is needed in your case.
