i have episodes where this happens to me as well. like when i think of something or hear/read/talk about something that has nothing to do with the theme of my thoughts, my brain will automatically want to connect it with intrusive thoughts.
hey alice, i was in a very similar situation as you are, but the pocd was not as bad as other taboo thoughts. i'm glad you have been diagnosed and put on medication. what you're saying all very much sounds like pocd, even the fear/thoughts of "justifying p" or when reading about abuse stories.
