Is she going to try and take her GED? I would be going crazy being 17 and having to take classes with14 year olds. I know she did this to herself and I suppose she will have to deal with the fallout.
Does she plan on you guys supporting her financially forever? You might want to put that thought out of her mind. Does she know what kind of job she might have to take without an education? How will she afford rent? These are the bits of reality you will need to show her. Talking about it probably won't do anything but showing her should.
