Wow. I am so sorry. I really don't understand why your T would not make the phone call, I really don't. It was not like she was "initiating" it, because you made the first contact. And it did not have to be a lengthy report. I really don't get it.
I think your letter is great and I hope you give it to your T, so that you can figure this out.
Who knows, maybe it is "her stuff" because if she emails with you, I don't get the problem with leaving a brief message.
I just don't get T's..... I really don't.
Good luck when you see T.
