get behind the eight ball

To find oneself at a disadvantage or in a challenging situation. An "eight ball" is one of the numbered balls used in the game of pool, and the last one supposed to be hit into a pocket. If the eight ball is accidentally hit into a pocket prematurely, the player will lose, and it therefore needs to be avoided. Our country is going to get behind the eight ball on this issue if we don't take action now. I got behind the eight ball on this project after coming down with the flu. I've been so busy that I've gotten behind the eight ball with my Christmas shopping.
