One thing that helps me a little is to "jump the chasm" and plan something for after T will be back? You know how when you are driving your car they tell you to look out, a little bit ahead, in order to steer well because if you look right in front, it's harder because you're going so fast and your eyes can't adjust (like looking immediately out a train or car window as the scenery whizzes by instead of further off toward the horizon/mountains :-) So, I plan "other" things for when T is away to present to T when she gets back; a simple diary of my experience of her being away; if it were now, I would start working on my Mother's Day party I have every year; some project I've wanted to do but haven't had the time/head space to work on it because I've been concentrating on T, etc.

I didn't always tell my job that T was away; sometimes I took off just as if I was going to my session and did something else! Sitting with yourself during T time, without T can be interesting!
