When I saw the title of your post, the old Dean Martin song popped in my head and I thought you were alluding to it.
Then I read what you wrote. Geez. I hope she is ok.
From a very young age, the majority of my interactions with other kids were negative, were often emotionally abusive, and occasionally, physically abusive. Similar to Smallsteps, I was a pretty decent kid overall, well behaved, and usually considerate, but that didn't help me with peers.
Yes, I was the same. Generally well-behaved, which usually (unfortunately) makes one a bit of an outcast from other kids. As you write, I think that taught me a lot about how the world works. It also, ironically, taught be a lot about how socializing works in this world. Those lessons have served me well.
But anyway, I hope your daughter is ok.
