Then your T should be apologizing to you for not being better able to serve you. If you are doing the best you can, you have nothing to be sorry about.

If you haven't heard back from your T by now, I'd resend the email with a note saying, "Did you receive this email?" And keep resending until she at least gives an acknowlegement of receipt. It's a total pet peeve of mine when people don't respond to emails in a timely fashion, though I do understand there are sometimes valid reasons for such (didn't get it, went to spam folder, out of town, in hospital, etc).

Keep us all posted!
