Thank you all for your replies, it's actually the third time this has happened in a year. She is always very apologetic and I genuinely don't know if she does it on purpose but given what I had told her about my previous experience with a t you would think she would be more careful. I am my t sure if she genuinely is in her own little world.
Before I left I rand and left a message this time and the last time. She thang back 30 mins later and she said she didn't have any excuses she was really sorry and embarrassed, she just said 'oh, my head' and sighed. When I went back to her after she rang about ten times and left messages, I was ready not to go back but she kept ringing and she sounded very disappointed with herself. I didn't want to leave her in that distress so I turned my car around and went back.
She was really good with me and I actually went into shock in that session. She put a blanket on me and made me tea, she told me to come back to her in an hour to go away and get some fresh air. I went back and we talked about what had happened for me when she wasn't there, the rejection, the feeling foolish etc...she was so sorry and didn't charge me for those two sessions. I could forgive that but the other times I am starting to wonder about her drinking a lot and forgetting appointments, I mean how else could you forget. Her office is at the back of her house. She rang two hours before that to confirm. I just wonder was it deliberate.
