Hi Groundhog
I'm appalled that you've been treated this way! I've read many of your threads on here, and you have certainly been through the absolute wringer - you need empathy, not mocking.
I'm really proud of you for plucking up the courage to call them and explain why you didn't feel it was working for you.
I find it quite heartening that the head of department rang you to confirm your complaint. This tells you a couple of things
1. You are not the only one - very often, you will get a call back that quickly when there have been other complaints
2. This psychologist has read your records and believes you need help and support
CBT is there to help you identify the issue, then put in place psychological supports of your own that you can draw on when you feel that wave coming upon you. In a way, it is a bit like telling the anxiety to shut up and go away, but there are many, many steps that need to be taken before you can even think to get to that stage....and they need to be handled sensitively, and you need to constantly practice them. This woman sounds like she was verbalising how you ‘should' be managing them, without guiding you, gently and with compassion and empathy. To be honest she sounds like a right b**ch, who is clearly in the wrong job.
I do hope you don't give up on getting the help you need. In the meantime, please be kind to yourself xx
