I agree. I think if T is back in the office T is trying to get back to normal. T will know how to take care of herself, hopefully. She should be fairly good about being able to decide if she's up to it or not. I certainly think acknowledging it is helpful, it takes a bit of awkwardness out of the air immediately. Like, we touched on it, it's in the room, and let's move on. I think you can certainly talk about your feelings, of how it made you struggling with your own turmoil, etc, and I'm assuming she will talk about how she can take care of her needs and is there to help you with yours during this hour.

Being out 3 weeks, obviously things have been tough. Being able to accept she may NOT be 100% firing on all cylinders. It does take a bit of time to get back in your groove. But you by no means have to "protect" your T from her own job.
