My T is also a prof. for a local graduate program. I had gone to that school and was even signed up to take her class the next semester before I got thrown out. Most of why I got thrown out was for being very assertive (you will note I say very, not too... sometimes it is called for). My T and I had talked several times before, just chit chat and hugs (I'm a hugger) and she knew my reputation. She knew I had a strong personality, a strong opinion and was not intimidated by anything or any one.
The first session with her I was Terrified and cowering and I must say it really caught her off guard. She recovered well though and asked very gently "It's different for you in this context isn't it? you seem very scared, is that what you are feeling?". 3 years of off and on work with her she is getting a little frustrated that she is still not seeing any of my assertive side...Just how it is sometimes. (Thanks for this BTW... was trying to figure out why she was so frustrated lately)
As much as I wish my T would hand me a worksheet some days it would just be being lazy and avoidant. I filled out a very brief form before our fist session and that's it. The more you share about your session the more my stomach turns and I begin feeling scared. "I printed it on the good paper"... GAG. "If you SI I will not be able to sleep at night"... Scared. That is just such an inapropriate response to someone who has a history of SI. That statement does not in any way set a safe theraputic frame, a safe place to grow.
Take advatage of the wonders of voicemail! Like Echos said, all you need to do is cancel.
