OCD can appear funny to someone who doesn't suffer from it. I admire the sufferers who can joke about it.
It seems to be more common than realised. My personal belief is that it is caused by extreme stress at some period in your life. Maybe more ex-jws suffer from it than the average populace. (Dunno why).
My darling sweet daughter never talked about our divorce - she always kept a bright outside. Her OCD would break my heart. But she's grown nearly out of it now. It takes time.
