Hi and welcome to the forum,
Your son both TSH tests are low, indicating hyperthyroidism, however, the antibodies tests are normal.
There is a third antibody test to confirm rule out hashimoto, that is called TGab.
TSH alone can cause lots of symptoms even if other numbers are normal so in my opinion a second opinion might be in order.
Hyperthyroidism can cause sever anxiety so does hypothyroidism.
Best wishes ,
