It sounds almost as if you're *curious* about what it would be like to not go to T or not have T's support. Curiosity isn't a bad reason to take a break. I think as long as you aren't keeping yourself from T as some kind of punishment, I think it's okay.

Honestly, I think you'd be better off going just this week and talking about whether taking a break would be productive for you. You don't have to open Pandora's box, but I think it might make sense to tell T that and process your feelings around taking a break. I think it would help you to talk about talking about it, and including T in these kinds of discussions may be more productive than you might imagine.
