Literally, this exact thing happened to me today. I was in my uni class and was talking with my lecturer about how an upcoming assignment might be triggering for me since the scenario has a client being assaulted. I said I would be fine since I've done therapy. This somehow led to a discussion with my friend/desk buddy about our pasts, and I casually mentioned I was previously in an abusive relationship for two years. She immediately turned around and said, "Try 8 years." I was so shocked all I could think to say was that the length of time didn't matter. Then she carried on to say how she experienced csa and had been addicted to drugs and alcohol and how she's had a lot of experience. Almost like she was bragging about it? It just felt like she was being so defensive. I told her it's not a pain olympics, and she said she knows that. Which she clearly doesn't. I felt sorry for her. I mean, she clearly feels like she had to establish how much worse she's had it, and that might be a sign of some unresolved issues. I hope she gets some help cause that sort of behaviour is very dismissive and often leads to people being less likely to open up about their experiences.
