Oh my God I would also be so upset! The therapist should understand the intensity of your reaction. I mean the relationship I have with my therapist is the most intimate one, in many ways, that I have ever experienced. it is more intimate than sex I think. It would devastate me that i would not have heard back from them but what I find is that often there turns out to be really valid reason for the delay ... the message was not received or something and all my turmoil and heartbreak was for nothing.
