my client canceled on me.

"i'll tell you the truth, emily. i just didn't feel like talking about those feelings. so i canceled. but... [long pause] i will see you next week."

one of the things i'm learning about being a therapist is how to deal with canceling clients. is it me? is it them? was it something i said? did i mess up? did i say the wrong thing? are they just having a bad day? is this avoidable?

it's a totally frustrating feeling that is heightening my inadequacies.
