I think the concept that she might be behaving in this way to purposely affect you is interesting. I have no idea if that may be true. What do you think? Is that the type of thing she might do?

For me personally, I wouldn't be bothered much by the things themselves as for what they possibly represented. I would be worried that a therapist who had recently started working from home was doing these things for the wrong reasons. Like, instead of just losing track of time, being more relaxed, etc., that she is taking her job less seriously and maybe not even seeing it as a real job. If she's not feeling towards it like a job, then what would that make me and why would I be paying for it?

In the end, I think you're going to have to go with weigh things out for yourself. Take into account your feelings, how those feelings might be influenced by your negative experiences, and your history with this therapist. You are perfectly right to be concerned about her behavior. But you also don't need to jump ship right away just because the stuff she's been doing is odd for a therapist. You could keep an eye on the situation for a bit and see how it develops. Observe if she is as attentive to you in session as before, if she is on top of things in the actual sessions - basically monitor the quality of your therapy in comparison to before she moved to her home.
