I have never had to switch therapists, but I did have to add an additional one in to be able to get the second letter required for surgery. Going in I really didn't know what to expect with her and when I went back with her for the first appointment I would have sworn you could here I pin drop. She realized I wasn't going to start the session and she decided to instead. True she was only required for a couple sessions to get the letter and we both knew coming in why I was there, but still who knew a room could be so silent for that brief moment. All I can say is be yourself along with being open and honest with the new therapist. I hope it goes well. Good luck and hugs.
