As everyone else expressed, every therapist works differently. In general, they accept your decisions to come or leave therapy. If you would have gone today, I'm sure she would have the time slot waiting for you, or I'm pretty sure. She may have read your e-mail as hurt and angry but not have understood that you were waiting to hear from her.

My t has been quite clear. If I need to hear back from her, I must ask directly, "please call me back". Otherwise she will not return a phone call or e-mail.

I think your therapist knows you are hurting. She is waiting for you to ask for the help you deserve. From my past experiences, when I have been really angry with my therapist, is when I learn the most about myself and the opportunity for growth that lies ahead. It sucks.
