This sounds like such a difficult situation - I couldn't stand all the uncertainty over when my next appt would be. With my current T my appt changes from week to week because he teaches& does other stuff in addition to his private practice. At the end of each session he schedules my next appt. Do you think your T might be able to do that? Hopefully he would know what his schedule was for the following week, so you wouldn't have to go through the uncertainty of waiting for email responses. That would drive me crazy!!! Maybe you could suggest this? He can only say no if it doesn't work for him, but at least you tried.
