P7... your option tomorrow is to either go and spill everything, or cluck like a chicken for 45mins, ok?
if your T is a psychologist or a psychiatrist (i'm not sure about counsellors) then they aren't allowed to spill to your work T unless they have your permission or believe you are in immediate danger. i would remind your T of that, if that is something you are worried about. tell them that you have no intent of acting on these thoughts, but you do need to talk about them in order for them to go away. at my old work place (hospital) they used to take client confidentiality so seriously - they wouldn't talk to another care provider unless the patient had signed a form allowing them to do so. so i think it is something your T needs to take seriously, and if they still 'threaten' you with that, then i think that's a discussion that needs to be had?
or, of course, you can cluck like a chicken. and hide behind the elephant.
