My 19 year old son has fallen down a dangerous slope and I am now looking for advice. Backstory: he had some speech/Occupational Therapist (OT) throughout elementary school, and was always very quiet and never interested in making friends. Come age 16, he began to refuse to get up for school and soon dropped out. From a young age, he would spend entire days playing video games with no desire to do anything else. He is 19 now, has never had a friend, has no social skills, and no general skills. When he is at his father's apartment, he doesn't have cable or videogames, and will sit in the house doing absolutely nothing for days at a time. Has absolutely no desire to leave the house. Doesn't seem happy, sad, anything. Has gained much weight. Not sure what to do. Any advice?
