My son is always in his room, all he does is play his computer and only come out to eat. He is 14 and a few months ago was always with the family and talking to us. Now it seems he wants nothing to do with us. We tried talking to him but he says he sees no change. We looked it up and we found that it might be sleep deprivation so we said he gets off his computer at 8 and goes to bed at 10, we encourage him to be with the family, but he chooses to go to bed instead. However he lays in bed and falls asleep at 12+ it is not normal to not talk to the family. What can we do?
