Emotional stress response. Sorry to hear your son is experiencing such stress about going to school. Was he in the hosp. for a CAH matter? How is he sleeping at night, how does he come home from school, happy? anxious? You need to pinpoint where his anxiety is coming from. Bullying at school or is it strictly the fear of getting sick at school. If its the sick part..then sit down with him and go over a plan that is part of....ask him what he needs to feel more comfortable. Fear and anxiety come from feeling like you are not in control of things...so he needs to feel some control. Look into having a person at school be his advocate...is there a school counselor you like and trust or a teacher he feel safe with? I think there is will be support for both sides of the issue re emotional stress and increasing meds.... I have children, two with CAH...one which throws 2 year old tantrums up to 30 mins.. I do not increase his meds....FYI. Hope some of this helps...Of course explore the med/tummy ache possibility too! Good Luck! Jill
