My initial reaction is that I would be really upset if my T did that. There have been MANY times where my T tried to go deeper into some topic and I told her "Nope. I am done talking about that now," and she let me change the subject. Always.

and the throwing a tantrum bit?! Oh HELL no!

All of this is to say I have no idea if your T is a good T or not. How long have you been seeing her? Is this just a one-off bad session? Have there been other times where you felt like she has missed the mark?

Mine missed it greatly last session, and I left really angry without really knowing why. I wrote her an e-mail after telling her I was angry and upset and I wasn't sure why. She wrote back apologizing for pushing something on me, and owned up to what ended up being an "off" session.

Her apology is exactly what I needed, and I know I can go in next week and we'll talk about it and it will be okay.
