What you said makes so much sense!
In comparison to the thought of T not caring at all, it does show me that she cares when she is visibly disappointed. It's just hard, because I've disappointed people all my life in one way or another, and I can't stand doing that, particularly to people I care about.
It's kind of a lose-lose situation for me. If I tell her what I need to in order to work on my own issues, then I get the knowledge that I'm disappointing her. But if I don't tell her, I'm not getting the help I need.
