>So let’s look at it. What other options did you have? Could you tell her to stop loudly to get attention from others/adults around you? Could you have gotten up from your chair and moved? Could you have gotten up and told the teacher you needed to be excused?

This is good advice. I feel like schools should emphasize these strategies and be as specific about them as you were. The standard directive to tell the teacher is vague, and it's not always that simple. And nobody wants to be a snitch.

Even if you get in trouble for getting out of your seat, you might at least have a chance to explain why, and if you end up getting in trouble anyway, it won't be for getting physical.
