He's always been quiet and reserved, but withdrew completely into himself after a trauma c. 5 years ago. He did really well in his GCSE just before that.
I've tried to get him to counselling many times, but he won't engage, so it would be pointless, and in any case a decent counsellor wouldn't see him under those circumstances. He's now 22.
He does attend his (min wage) job regularly and must have to deal with people there, but I don't know to what extent he engages.
He barely leaves the house except for work. He's very good at helping with DIY etc. when asked, but never makes any attempt at conversation. Not with me, his brother, GPs or any visitors. I've often asked him to make an effort because it's rude not to, but he genuinely seems unable to.
He spends a lot of time online with people he's never met. He's currently talking a "friend" through a software issue. He sounds like an expert , but more than that he's engaging, interested, interesting, funny.
How can we bring that out of him IRL? I feel like there's so much potential, but don't know how to reach it.
