Please seek the care of a Board certified geneticist (not a counselor) for diagnostic evaluation and testing. A blood test for the Fragile X gene as well as other tests may be recommended. Your family history will be key, so ask other family members about mental retardation, behavior disorders, and other potentially familial problems before you go. The geneticist may work with a psychiatrist (as I do) or may refer you to a behavior specialist for help.
