I can understand that the agitation and frustration is from the fear of his future and other things. My mother faced something like this and I think still she is. I feel sorry for her and the worst part is I am not able to solve it. But on the brighter side, I now got a job in a fortune 500 company with a real good package and I just love being around my colleagues. They are great people. However I still stutter. So dont worry, he is young and he still needs time to understand what is happening and what he is undergoing. I wouldnt say or advise you to pretend, but rather understand. It takes time and by time, its not days or weeks. Maybe more, but through this process he will understand a lot of things, explore lot of other stuff, that others would not. Trust me, the comfortable and accepting environment would definitely make a change. Also dont worry, we understand you, my mother would have felt the same. But Trust me in this, a calm and comfortable environment will help him a lot. He is not alone, he has us and the world!
