i had this exact conversation with my therapist and he said the exact same thing it is one of the worst things you could say to someone with ocd   firstly it acknowledges that the ocd thought is “real” in the first place we all know that it is irrational  secondly as someone with ocd my mind has now convinced me that i must feel intense amounts of shame and guilt regarding every single possible transgression in order for me to be good that letting anything go moving forward not caring so much  etc is something only bad people do
