I am not a doctor, but would say its probable you have PANDAS/PANS.
If it were me or my child, I would not bother with the cunningham panel, but would invest time/effort/$ in finding any infectious disease that you may have (such as strep, lyme, mycoplasma, etc.). Also have your tonsils and sinuses checked for infection. There is a whole host of other things that can be done, this is just what I would do first.
