Here it is!

Dear Screenager,

everything's okay. I'm very busy now so shortly before my vacation, but I would have replied today at the latest anyway.

So unfortunately I can just give you this short feedback: It's completely right to write about your feelings and thoughts. And it's good to have feelings, even if they hurt or are uncomfortable sometimes.

Be strong, and see you on the 5th.

Your
T

So yay, she's not mad!
(Though I have to say that this cryptic "Feelings are okay" seems to be all she ever writes in response to something like this. But let's focus on the good things )
