I would try to approach it as a mystery. Your T says she truly cares for you and only she can know if she does or not, so you have to take her word for it. I would look for evidence If you are not "patient #139," what does that look like? (Hint, is she just therapist #5 or are you interested in working with her, because you like her method, manner, ease of talking to her, what she has to say to you, etc.?)

It is nice if people like us but we don't need that to have them help us improve our lives; teachers and other professionals come to mind and how we can learn from them whether or not they "like" us or we're just client #139. Therapy is a little like school and a little like best friends and a little like work and a little like working on your favorite hobby and a little like home. If it does not feel like the one you are thinking of right this minute, check it against another?
