You could use it as a teaching lesson for them.
Why not a letter or email ?
It is so hard to remember everything with a face to face (confrontation??) to each of those teachers, and it was a long time ago.

You could write out all of this and let them know how it affected you, just because you had no diagnosis back then..
With a letter or email they will have time to think about it and soak it in- better for them to learn that way..

It might be worth it to write it all out , like you did here, just to get it off your chest, then let it sit awhile a decide if it really is worth sending it to them.
