I tend to agree with Pachy...take a wait and see approach. I know MANY time in my therapy when I T said something that really pissed me off or made me feel like she was deliberately playing games with me. But often several days later... I realize some benefit either from what she said or my reaction to what I thought she said.

Take your time, allow yourself to react to the session, find a silverlining if you can. Leave yourself the option of going or not. If you decide to cancel... give the 24-hr notice.
