zoo...I know this feeling. Once my T's lack of response sent me over the edged and I did in fact cancel my appointment and vow to myself that I would NOT return to therapy. Luckly after a few days and some chatting here on PC, I call and schedule one more session and then things got better from there.

I say...honor your feelings of being alone and of your T not being there when she said she would be. But also leave some room of other circumstances beyond her control that might have happened...like her not getting your voice mail, or getting it and accidently easing it, or....whatever. If you can I would go to your next scheduled appointment express your anger and see what happens from there. I know my session after I quit was SO challenging to get myself to actually go...but what happened during that session turned out to be REALLY important.
