Anyone know of any good movies and books (particularly movies) that are good representations of ocd? I'm trying to find different ways of expressing how I'm feeling maybe through images and metaphors and I don't really know where to start

Looking for inspiration

I love horror movies and would watch them random sometimes even Terrifier cause art is my new favorite character. I just felt like I was a bad person for this⁉️ I don’t support his actions but I like his goofy faces he makes. I can’t enjoy anything no more Literally me rn in life

Someone I care about has OCD, he often gets worried to answer certain things in fear that he might be wrong or gets anxious in times when certain conversations such as dealing with negative emotions come into play and in the event something goes wrong even though we deal with the issue it takes him a long time to put himself back together. Often times worried about his image, hyper focused on being a good person etc etc. I believe I’m doing my best but as someone who doesn’t struggle with OCD I cant fully comprehend him and i wish to learn more about it, not just read it off of google. Any advice would be appreciate it. -Thank you!
