This is a good idea! I had a break from My T for a few weeks, and I did go out and do something for myself during the time I would regularly had session. I made sure to promise myself I would focus on my own stuff and no one else's during that time.

You might be missing you T, but if you can think of a way to do something 'therapeutic' while they're out, just do it.

Go for a walk, take yourself to a movie, journal at the coffee shop, get some exercise, paint, play, dance in your room, whatever feels good to you. Dedicate that specific time to do it- so you can look forward to your usual 'session' time just like any other week.
