She is sooo wrong on so many levels. Her e-mail was a snow job. This lady has some big problems. You have gone out on a loooong limb trying to accomodate her unprofessional behavior and she's still not willing to acknowledge her actions. I have 2 words of advice for you.....
DUMP HER NOW
I had a very similar situation with my last t. I saw him for 3yrs and the last year, he started cancelling about every 3wks. It drove me CRAZY and made me feel so insecure and unimportant. When I tried to talk to him about it, he said " you're the only patient I have that feels this way"

I knew it couldn't be true. Well, long story short.....I got a letter in the mail the day before my next appt. saying he had closed his practice due to "personal issues". I swear, I grieved like somebody had died for 3 months.
I finally decided I needed to see somebody else or I wasn't going to get thru it. I was lucky to find a wonderful t. who helped me recover from what my previous t. had done. I have been seeing him now for 2 1/2 yrs. I am so lucky to have him for so many reasons. I will add that he has only cancelled one time, and that was because his mother died.
I really hope this works out in the way that is best for you. I can really relate to how this situation has affected you
