I think it's normal to desire approval from your T. I think of it like this - if my T, who knows most of my worst secrets and things I'm deeply ashamed of, can still accept and approve of me, then that means I must not be a terrible person after all. So I can understand feeling hurt when your T expresses disapproval and seems to be failing to empathize with you on a particular issue. I've been there before and it's very frustrating, I hope you can work this out by talking it through.
