Question about my friend, anyone?

Loosing a parent when your young is very hard. My mom lost her mom when she was 37 about 3 years ago. She was crushed for about 5 or 6 months she would randomly cry. You need to tell him straight up that he needs to change the way he's living. Explain to him that he would feel better hanging out with someone that cares about him and not playing online games that people dont really care. I wish you the best of luck.
