What I can't figure out is how you even know about financial issues?
That right there is bleeding boundaries that causes issues.
A clients only financial concern should be their own arrangement with their T. A T has no business dropping breadcrumbs of info about their financial situation.

Is she specialised in eating disorders...Because guilt tripping you about how ' She hadn't eaten because she was expecting to eat with you,' sounds like the opposite of not making food an issue.

I do wonder sometimes exactly what it Is T think they are doing.
Fingers crossed you feel better soon and kind find someone who knows what they are doing.
