You already have said you feel guilty. Your feelings are yours, not someone else's/"out there". You can up and quit and feel guilty for doing it that way or you can do your best to deal with her questions and your feelings of guilt in a last session. We generally feel guilty when we do something we feel is wrong. It sounds like you feel it is wrong to quit seeing your therapist because you do not feel you are getting enough from the relationship. You have to decide what you want and stand behind yourself and what you want. It's your life and living it worried about the other person and what they may/may not think and feel and what they are doing (Can they deal with their feelings??? What if they can't, it will be all my fault!) means you are not respecting yourself and living your own life. Personally, I would stay and work with your feelings of guilt around leaving, with this T, since she seems to elict them so nicely?
