I still remember the depression I went through at about the same stage. Just give him some space . He has to find his place in his new world. It takes some time to work it out. I am still to this day discovering "new" things I can or can't eat, especially in public. Do you guy's like to hike? Maybe just a very short hike, nice & easy, in a very beautiful place in the woods or on a mountain would help his spirits. Encourage, but don't push. Then again, sometimes a good kick in the ass is appropriate also! Tell him to get on this board & check it out. Erik
