Well, I didn't manage to talk fully about the incident, but I did get to tell her some of the flashbacks and things that I am dealing with. It was helpful, although right now I am feeling like it is more real than ever. Grr.
But I guess that is part of healing too, right?

She did suggest making like a "safe place" to replace the flashback images with, which is actually helping me fall asleep better at night. So, all in all, glad I went. Kinda looking forward to next week; maybe I can actually open up about it all and just let it go. Who knows? Thank you for all the kind words.
