I can understand why you're frustrated. I guess I would suggest going to the next session anyway if you can and hearing your T's side of things.

There have been times (earlier this week, for example) when I'm really mad at my T and feel like there's no point in talking to her anymore and that she is purposely doing something mean to me. And then once we talk about it, I start to see her side of things too, that maybe she wasn't doing what I assumed she was, and that makes me less mad. So, I'm just saying, sometimes it helps to get the whole picture, even when you're mad, and the only way to do that is to let the person you think has hurt you have a chance to offer their side. That is what I've been working on anyway.
