Tips for working with teen boys?

Been working with a 15 year old boy dealing with depression and feelings of loneliness.

He’s very intelligent and self aware. Admitted on the first visit he felt sad and alone a lot. Also told me not to tell him to “just join some clubs and meet new people” or he was never coming back. Tells me to be straight with him and not beat around the bush and not to worry about offending him. He’s not super resistant to therapy but doesn’t think it will do much good.

He’s really quiet. It’s pulling teeth to get anything out of him. Not interested in playing any games. Says he has no interests or hobbies. Nothing he wants to talk about. I feel like I can just feel the sadness and stress on him when he walks in the room. He’s very tense and I feel like I’m struggling to connect with him and get him to relax. He keeps coming back though.

Any tips for working with this demographic?
