Thank you so much for sharing your story with the forum, it is great that you are trying to find ways of supporting your son, not easy when he is refusing help and treatment of his anxiety.
It does seem like he is quite busy with everything and perhaps that is his way of avoiding dealing with the core of his anxiety. Sometimes addressing the source of the problem can be quite distressing and difficult, but the most that you can do is keep checking in on him to see how he is doing and offering support if he wants it.
It can certainly be a tricky balance of giving him space to manage things in his own way, a way that works for him which is different to how you would manage, but he needs to want help for it to make any difference. You can perhaps calmy tell him your concerns, when he is also calm, and see if he needs support in any way that he finds helpful.
