Sometimes I wonder if this is actually a therapy technique to test your ability to challenge yourself - I've seen too many people go through this type of thing and I've gone through it before as well. I used to refer to it as frustration therapy, she would frustrate the hell out of me sometimes with wrong appointment times and then when I'd get back in she'd want to discuss it in detail, (my reaction).
I was so mad each time I was seeing red, so I completely understand how you feel, but by the time my next appointment rolled around, I had other issues to deal with and I usually forgot how I had been feeling...or at least, didn't let it get in the way of the relationship.
It may be difficult but write down how it made you feel and then let her know in the next appointment; in order to have a good working relationship, you have to be honest with each other. Remember that honesty does hurt most times too though, but that is what needs to be done.
