Anderson Cooper talks about OCD

Watching the TV show Anderson about Obssessive Compulsive Disorder.  My husband has OCD and I am glad it is being addressed on television,  Just to make us all aware of this disease. Howie Mandel is about to speak as he suffers from it.  Living with someone afflicted to this is difficult, but I try to ignore so much of his behavior.  I wonder if this has made me strong or callous.  He moves furniture constantly claiming he is searching for the right arrangement when I know there is no such arrangement to satisfy his agitation. I don't know how to help him, but just try to go on with my life.
