How can you get someone to get help, he is 18 so I can't force him, he is not interested in anything doesn't even said words just nod, no friends, this has been going for the last three years I gave him a break moved with other family members thinking things will change, denies suicidal thoughts or hearing voices, been diagnosed with ADHD at a young age, was a happy child, very funny and interested in sports, he eats, takes showers, when I have taken him to Psychologist he just denied any mental problems, doesn't want to see whether virtual/person counseling.
Please give me your inputs, anything, is very hard to see a young person have the young years wasted away.
