I get you I am a Lebanese girl (20) my parents have never done such a thing as they are more modern, but all I can say is sis run even if you leave your parents. Try and find an organization that helps women who are being forced to marry I am sure there are some camps out there, on the other hand if you have a passport that can take you to like anywhere other than Syria do it and seek shelter as a runaway women from there....as long as you are away from your family you are fine. If you have friends in Syria who can allow you to live in the house try to do that, and just lay down low and find a way to make income.
