(((((turquoisesea))))) I'm sorry you're going through this right now. I had a similar experience last week. My session time got confused because she had to reschedule me, and my parents didn't know that my appointment was at 5 pm - they thought it was at 6. The receptionist called at about quarter after 5, telling my parents that T thought I was supposed to see her that day. I started freaking out and crying at the thought of not seeing her, it's like this signified losing her to me.
Can you perhaps make an appointment with T and explain to her how she made you feel? If you do decide to find a new T, I hope you get one who is much more caring and supportive
