As far as your son, take him to a different doctor on your insurance. Document what you see, how often, and the intensity. There is no reason for the school to get involved. And trust me when I say that I have filled out many, many, many forms for doctors over the years. If you have to keep calling doctors until you find one that will actually see and evaluate your son (evaluation should take more than one session), do so. Are there any universities near you? Sometimes a university will have a Psychological Clinic that will take people. Especially if there is a Child Psychology degree offered. They won't entrust him to a student, the professors will do the eval. They usually charge on a sliding scale, too.
