Have you thought maybe why actually you "mustn't" take your T's offer? Why do you have so strict rules with it? Could it be that you just don't want to accept that she really cares and that she's not a T because of a good salary but because she wants to help people, she wants to help you and she cares about you? I don't know but I think that would be the biggest problem for me, that she could really care... When you pay - you are the boss, you can control when you come, if you come, if you want to fire a T etc... when T decides to do sessions for free, it means that she wants to do that...
