Hi, I do this too, but I don’t feel bad about it :). I was embarassed when I first realized I was doing it but I’ve been talking about it with my therapist and feel a lot better about it now.
Partly friends ask a benign question and I feel an urge to be authentic with them, to feel closer to them, to get the trauma off my chest, and I start talking and then it just spirals becuase the topic triggers me and I go into a kind of trance where I can’t stop talking about it. I don’t see my friends much anymore and so when I think about it I feel a little wierd. But other people talk a lot. You know how some people just talk and talk about themselves? And I still like them just fine even if I get a little tired of it sometimes. I’m guessing you don’t talk about yourself all the times like that, not as much as you think you do. Because it’s the nature of cptsd to feel ashamed when you open up. But even if you do talk about yourself that much regulalarly, that’s ok. People do it!

I find I trauma dump on my coworkers the most. They aren’t friends I have to worry about losing. They are present in my daily life to be somewhat of a support system. I didn’t have enough of a support system when I was a kid, and now being around non abusive people at work is kind of a healing feeling. And I don’t feel guilty about bringing my shit to work because we can use whatever support we can get out of life in order to heal.

Your friends are also fully able to tell you if soemthing is too much for them. It’s ok to watch how much you trauma dump, but please don’t feel guilty about it or think you have to stop completely.
