I really fucked up

I don’t really know what happened. I feel like I’m really good usually about not sharing or being very choice when I do. But I was tactless today and shared a big trauma during a session as the therapist 😬 . About loosing three friends in a fire. I’m just so upset with myself for trauma dumping on someone who just processed putting out a fire. And my client was shocked and upset. We talked a lot about it after I brought it up and there was a reason I did and loosing those people was not what the point was but that we as a community really cared for each other and that my client felt they carried the responsibility themselves, what I wanted for them was to be supported by the community they lived in. Anyway it obviously was fumbled, to put it nicely, and I acknowledge my tactlessness and I apologized, and we actually did more EMDR around it. I don’t even know what happened and I feel deeply remorseful. I’m just like what the fuck did I do?
