My former t and I had switch appointment times once because of her scheduling. I had forgotten to set an alarm to remind me, and I hadn't paid attention to my phone altering me to the appointment. I was bopping around doing art and being bored when she called. I had no excuse, but she was understanding (hadn't missed an appointment without calling in the year I had seen her). Stuff happens sometimes... hope you can get in to see her as needed, and hope you can get some rest.
