Hi Guilt and Cookies,
Maybe an affirmation, “I forgive myself for anything/everything I did before I was eighteen” or “I forgive my childhood self” could do the trick.
Kids do a lot of gross, crazy, and inappropriate stuff. They are, by definition, immature. Meaning they are half baked. I knew kids who hung cats in the woods. You think they feel guilty now? If they do, they’d never admit to it and moved on. At least you are tormented by guilt. But how much longer are you going to beat yourself up?
Best,
Inky
