Try not to stress over the pizza deal, she was probably just being nice.

I get where you are coming from, I was the kid who never quiet fit in. I'm probably "on the spectrum" somewhere but it wasn't as well understood back when I was growing up and so I was never diagnosed. I have nephew with autism, and other family members with adhd and I would bet if I were to be tested today I would have one or the other if not both. At least you're starting to figure it out while you are still young.
