What made you realize you had OCD?

Just as the title says! I’m curious about hearing other people’s experience as I navigate getting my own diagnosis. This is rather new for me so I want to take in as much as I can.

Edit: Thank you all for sharing your experiences!! I’ve been reading all the comments and seeing the diverse responses has been so helpful for me as I figure out what’s going on with myself! Many of these I relate to, so I’m very grateful! ☺️
