Wayfarer25, my T doesn't communicate through email either; just by cellphone but I usually get her voicemail and she calls me back in a fairly reasonable amount of time.

Like Willow, what I have found to work for me in the past is that I wrote down what I needed to say and read from that when I called anybody. It helps get the initial concern across without sounding jumbled. I've also brought my journal in for my T to read particular entries to discuss because sometimes my head is not in the same exact place as I was when I was writing the entries. Also my memory can be a sieve in remembering things sometimes so writing things down really helps.
