Aurora,
I am so sorry this is happening. I do know that OCD is usually considered an anxiety issue as we have many posted in Aniety.
I know that meds are helpful and perhaps your son needs an adjustment in his meds. Of course I realize med adjustments are tricky.
CBT therapy is one of the suggestions I have read that has helped many members.
Great links posted and hopefully between the links and Karen's assistance you will get more helpful info.
