I'm sorry you're struggling so much. I know it can be difficult to reconnect with a T after a break. And if she hasn't really been working for the past 3 weeks, maybe she's kind of off her game, too? Like if she'd been seeing you regularly during that time, maybe she'd have been better able to pick up on how you're doing. And I agree that some of what she said seemed insensitive.

I agree that you should reach out to her. Even if she wants to wait to talk about it in session--I think you said you see her Thursday?--then telling her over email that you're really struggling would make sure you'll be able to address it in session. I think the following thing in your original post would get it across well: "I feel so terrible that I feel incapable of doing more than I am currently doing. Which, now that I mention it, is getting to be less and less. I am decompensating and can barely manage to get out of bed, feed myself, and bathe. Sometimes I do none of these things, and only get out of bed to feed my dog." I've found that sometimes you need to really spell out your symptoms, and how they're affecting your life, to a T for them to understand.
