Q: Our 18-year-old daughter is a month away from high school graduation and she is failing nearly every class! About six months ago, she took up with a group of young adults who are less than desirable, to say the least. Some of them are dropouts. I suspect drugs and alcohol. The more we tried to prevent her from running with this lowly bunch, the more rebellious she became. Finally, in desperation, we took her car and her smartphone away and told her she can't have them back until she possesses a high school diploma. If she fails to graduate, she can go to summer school or get a G.E.D. from our community college. She says she's not even going to go to school at all until we give her the car and phone back. And she adamantly refuses counseling. Help!
