What do you believe are appropriate expressions of feelings and emotions in therapy?
I think, as long as it doesn't resort to violence or serious crossing of lines, most things are fair game.

What are your therapist’s boundaries? I am particularly interested in the negatives.
*sigh* I don't know. The boundaries are where I struggle. I know mine are more rigid but I don't know where T's are.

How does or would your therapist respond to expressing anger towards them?
T responds with excitement. I do not show anger often so if I am willing to express it in a session, it's a big deal.

Have or could you tell your therapist you hate them?
I tell T this often, but we both know I don't mean it.

Is raising your voice in session acceptable?
Absolutely.

Do they allow angry phone calls between sessions? Angry emails?
Iffy on the phone calls but definitely the emails are ok.

Have you ever accused your therapist of hurting you? Or not caring? Or not being competent? Could you?
I have talked to T about mishandling a session and how that hurt me, it was a hard conversation but one that ended up being incredibly productive. The not caring thing comes up often, T insists that it would be impossible to do that job and spend that much time with a person on such a personal lever without caring.... I am less sure about this.
