The pictures don’t work with all ocd. Often times I would worry that I did the thing that couldn’t happen (open door, whatever) AFTER the picture. So I’d videotape the situation and myself walking away. It got silly. I really hate this condition.
Just recently went through my phone and spent an hour deleting all the photos I took of appliances, etc. I had taken during the height of my OCD. It must have been hundreds of pictures.
