I decided to call and leave him a voicemail...

It basically went like this, "Hi T, it's MUE...It's Friday night. Hope you're doing well. I feel it's important that we have a conversation prior to my session Saturday, because I'm feeling quite irritated at the e-mail exchanges that took place today and want to clear the air. I am feeling disappointed and hurt that you continued to pressure me to make the DYFS call without giving me a few minutes of your time to discuss how I could provide the necessary details to them in a safe way for me. I absolutely understood the need to follow through on making that call and that legally it needed to be done, quickly - but instead of spending a few minutes of your time to help me with structuring the call in a safe way for me, you persisted to send e-mails - which you apparently found time to do - that felt demanding, threatening and uncaring towards me. In order for this next session to be productive for me, I need to feel safe and cared for....and at the moment, I'm feeling untrusting. I'm not sure what I need to hear in order to feel better about this, but I need you to call me."
