Wow, I'm sorry that you had to go through that. I would have been over the top angry if my T pulled a stunt like that!! I get irritated when she's running 5 minutes behind but what you've experienced is completely unacceptable!
I think there may be some truth about the really good therapists being out of network, mine is. Some people may disagree but that has been my experience. I hope that you find a therapist that meets your needs and in a timely fashion😊
