That's great that you were able to mention it, since now, like you said, she'll ask you about it. And handing her something written is easier than having to say it all in detail. I've given my T a few written things before--it is very difficult sitting there while she reads it, but then I don't have to worry about getting the words out (plus I express myself better in written form). You could probably just use what you've typed out before on the board, maybe modifying it a bit if you want. It also helps that she already knows that this is causing you great pain--so when she's reading it, she can have that in mind.

Please stay safe and take care of yourself.
