Take the money you would spend on college or obtaining GED, food and living costs, add it all up. Now, write a check to your daughter for this full amount. Then tell her she is released from your presence for the sake of your long term well being. Then don't contact her for 10 years, or ever. You will think this is an insult or joke, but I'm dead serious- this is the only option that will work for her benefit. If you want to be that fix-it helicopter parent who saves the day, and you got to get your fix, or definition for existing through actions taken on your daughter's behalf, then whatever. If you were dumb enough to send a kid to "wilderness" then we already know the answer to what kind of direction you are headed.
Daughter. If you read this, get out now. Just do it. leave. get out now! right now! Or if you stay, be sure to bring up the akward situations from wilderness during dinner for laughs. "Hey mom this meal kind of reminds me of the beans and rice I ate when forced to hike 10 miles in the desert, THANKS AGAIN FOR THAT".
