So I met a new friend... she seemed like she had an admirable goal of helping others with trauma... it's her life's mission. But it seems like her traumatic background defines her so much so that she awkwardly interjects some reference to her trauma every 10 minutes or so in a group setting and one on one. And there's a subtle oneupsmanship whenever I explore trauma theories with her kind of like since she's been through so much she's automatically the expert on the subject. I can understand how this could be a massive defense mechanism on her part. How should I respond to her constructively and supportively? Have you ever experienced this?
