What do you do when your son doesn't want to go to therapy

My son has therapy today. He's 15 but when I told him to get ready he just pulled a blanket over his head and said he doesn't feel like it. Therapy is part of his probation. He's already been to Juvi . We've been doing well going to therapy but he was refusing to go today because he didn't feel like getting out of bed at all.... I'm not sure what else I could have done so I let him be after trying to get him out of her. It's the only session he's missed in 2 months.

@Molly I wasn't trying to tell him I'm okay with the consequences. I just didn't know what else to do besides physically drag him out of bed. I spoke to his probation officer and she just said okay but not to make it a habit. I've been struggling with him more lately. There are times where he's lashing out and saying he doesn't care. Send him back to Juvi. He doesn't get violent. He just gets mad and last time he got like that he went and destroyed his room. The reason he didn't want to go today is because he's tired of talking about his trauma and has been talking about it all week for legal purposes and he is mentally drained.

@G He likes his therapist. We've just been meeting with people everyday except New Years this week. There's my son's legal stuff going on because he went to Juvi on an assault charge. Long story short his got angry with baseball and his coach touched him to calm him down and he lashed out on his coach and hit him with the bat. He had already gotten in trouble with vandalism prior to this. So we have had to meet with his probation officer for that. Then we've had to meet with one of the detectives handling his case that involves traumatic stuff that had led to him lashing out at people. So everyday except New Years we've either been at the police station talking about trauma or with his PO talking about how it's going working through that trauma.

@Molly I should have clarified. What I meant by violent is he wasn't hitting anyone. But most likely because nobody touched him. He doesn't like being touched. As for the the Juvi thing sometimes it feels like he prefers to be in Juvi because he's just given up on life and that he could be anything other than a delinquent. We've all been through a lot dealing with his behavior. His outburst from his trauma. Sometimes it seems like he wants to be comforted but refuses to accept it.
