I've been looking into OCD details because I think I might have it, but I'm not really getting very far. My "obsession" is taking pictures and writing things down in journals so I don't forget the past. I NEED TO KNOW the things that happened in my past experiences or it doesn't feel right. I saw a post from someone who had the same problem, and they said their therapist said their obsession was that "need to know" problem, and that they had OCD. I never saw this type of OCD while researching it though, so I'm after verification.... Is this info right? Could I have OCD?
