The way one of my T's explained it to me is that we as humans get over trauma by communicating the trauma over and over again until it no longer effects us. Like is someone got into a car accident and then went to work and told the whole office about it. They may be Chatty Kathy but it is also because it helps them work through the trauma. For this reason I'm rather forthcoming about being abused if it adds to the conversation. I usually don't go into the gory details so to speak because I find it makes most people uncomfortable. Everyone is different though. I know it might not seem very insightful, but really its ultimately your decision what you want to disclose and how much you want to disclose it.
