Rules for myself:

No scarring T
Respect T's boundaries and privacy
Remember that she's on my side
Limit the clinginess
Show up on time (inform her if I'll even be a little late)
Give as much warning as possible if I have to cancel
Show up even if I don't want to
Be honest
Be as open as I can
Try not to side-track
Accept her strengths and weaknesses
If T and Pdoc team up: give up and listen to them
Limit out-of-session contact
"Call the crisis line even if I just need someone to talk to" (I have been told this probably 10 times now...lol)
Prioritize my coping skills (don't just do the easiest ones)
Try to live my own life outside of therapy
ETC.

For my T:
Must hug
Must be herself
Must be honest
Must communicate
Must be clear
Must be consistent
Must balance support and challenging me
Must be able to laugh especially when appropriate
Must avoid "mothering" me
(My T does all of these things)
