If I can relate to anything here, I can relate to the sense of shame.

I had "something" happen to me when I was eight with someone older than me. I have suspicions about what happened (abuse of some kind), but I can't narrow them down. However, what I remember clear as day 20 years later, is the overwhelming sense of shame that came from it. I can agree on an intellectual level that it wasn't my fault, especially when I don't really know what "it" is, but when I dwell on it, I wonder if eight year old me could have done more. Then, I start getting angry that I have to feel ashamed about what happened and around and around it goes.

If I had any "easier said than done" advice: Be kind to yourself. Treat yourself to a night out (or a night in). Be with friends or family. Talk more to your therapist about it. Do what you need to (within reason) to mute that insidious voice, if only for a while.
