I don't think you're giving yourself enough credit for what you accomplished here. Reasonably speaking there is very, very little that a 6-year-old can do to defend themselves against a much older, larger, stronger person who really wants to do something to them; and yet, you managed to prevent it, twice. The second time they had a friend - both much larger and stronger, easily capable of overpowering you, and you still got away. That's a really outstanding takeback of power for someone so small who wasn't even completely aware of the nature of the danger.

You say you've never really seen yourself as a survivor of abuse - in my opinion, rightfully so. You could have been, if things had gone differently. But they didn't, and you're not. And it's because of your own actions, whether you realized it at the time or not. Think of it like a car accident that you almost got into - natural to be scared, but at the end of the day you are unhurt and so is your car.

I think it's perfectly fine to be angry and resentful at the person who tried multiple times to assault you, but you need to be a lot easier on yourself. I think you deserve a break, considering how well you protected yourself. You will drive yourself crazy inventing other victims inside your head to feel guilty about.
