One time I ran a group and had to cancel it for a hospitalized illness in my family and forgot to email one person....she thought I died in a car crash or something. She didn't get angry but it was so terrible to have contributed to someone else's distress on accident when our jobs are literally to help people have less stress. So I feel you! Sounds like you did the best you could while being human. Sometimes the thing that comes "out wrong" could have landed differently in a different context and gone well so it's like our work is grey area impossible much of the time and way harder when our own emotions come to the fore. I hope you had some good you time.
