I suspect she does feel like she's been hit by us bus (and that description isn't particularly sarcastic; really just metaphorically descriptive); I don't see how her describing her physical discomfort says anything at all about you not caring about her. Unless you've left something else off, it just sounds like her describing herself, not making any kind of allusion to you.

Telling you to use your tools isn't invalidating; it's just a reminder. I suspect she very well knows how difficult this was for you. Did you ask her to help you work through what you needed to work through? Did you ask her to work with you on those skills? Or were you waiting for her to read your mind about what you needed?

I also don't read her asking about next week's schedule as saying "if u won't listen, then I can't help u". Sounds more like she clearly understands you are angry because she has been away for a few weeks (rational or not) and that she understands your ambivalence about therapy right now because she knows the separation was painful and difficult for you. She was acknowledging your anger toward her, but I don't see in what you quoted any statement about meds or any implication that you should find another T.

If you wanted to discuss your emails, why didn't you bring them up?

I think she absolutely mentioned how hard it was for you (see all of the above), maybe not directly, but she seems to clearly understand you had a difficult time and are pissed.

Kind of sounds like you are still in a place of anger with your T for "abandoning" you these last couple of weeks and instead of being direct with her and specifically telling her what you needed or what you were feeling, you were wanting her to figure it out all on her own (maybe as some "sign" that she cares?).

You already have shut down, which is why your session wasn't particularly productive. You are going to have to really talk to her about how you've numbed yourself out (maybe so you won't get hurt) and how you truly feel about the experience of the past two weeks. It is up to you to be honest and forward with your T here. Only then will you be able to move beyond your anger and move forward in your therapy.
