This is actually about my brother, but I was hoping for some advice on what a parent should do about this situation. My brother is 22. Since graduating from high school he rarely leaves the house. He doesn't have a job or go to school and he doesn't appear to have any friends. He spends all his time either on the computer or harassing his mom and younger brothers. At one point last year he didn't take a shower for an entire month. When I, or anyone else talks to him about going to college or getting a job he'll give some lame excuse for not doing so.
Does anyone have any insight into what's going on with him? I'm conflicted over whether he has a serious mental disorder or whether he's just being a lazy bum. He had a troubled childhood though none of his siblings is a complete shut in like him. One of our siblings has psychotic bipolar disorder though. I sort of wonder if the shut in brother is in the prodormal stage of a serious mental disorder. Any insight?
