My panicky feelings are greater when trying to sleep. It's quiet and your mind can run away with itself! At times I could feel my heart pounding against the bed. I am on Lamictal which has helped. I also take 10 mg's of valium at night for fibromyalgia but it helps to calm me too. I would suggest going to a psychiatrist (if you haven't already) and maybe you can switch from a pediatrician to an adult doctor (not sure of your age).
