I have very little to contribute other than my heartfelt hope that your little guy gets better. Anxiety is horrible. And when you are young, so difficult to put into words. It seems like so much is bothering him it is a less of a 'what' issue and more of an issue developing coping skills. If school resources aren't a fit, I would look into a Psychologist to work with him on skill building. Lots of work insurance plans cover this service. Sending you a hug.
