I also have proposognosia and I have difficulty recognizing my own face and people who I've known for a very long time. Like for example my sister used to have super long hair and then one day she got it cut to her shoulders and I literally didn't recognize her until she spoke. I feel really bad because I'm also super bad at remembering names so often times if someone mentions or points someone out to me I'll have no idea who that person is. It's really frustrating. I also can't tell people apart in movies and such unless they have a particularly unique hairstyle, clothing style, gait, etc. Which is one of the main reasons I watch cartoons more than live-action stuff.
