My T is out of town for a few weeks as well. Thankfully I have a great relationship still with my old T (who I stopped seeing due to a combo of logistics and wanting to work on something, for awhile, I needed a male T's help with) so was able to meet with her in the interim. It's been good to catch up with her and use the time to take stock of where I'm at and how things are going since I last saw her.
In the past, particularly when I was at a point where dependance on my T was a "good" place to be in terms of therapeutic value and I was seeing her multiple times a week, a few things helped. Besides the obvious (permission to text/call if in crisis, a planned check-in, etc) I found it really helped for her to write me a note before she left stating a few things that were true about our relationship and that they wouldn't change while we were apart. (Tried that as a voicemail too, but that didn't work as well for me) Also reading a book (usually one she recommended and we agreed on in advance) during the break, and highlighting sections or making notes of things I wanted to talk to her about helped.
If you have supporters outside of therapy, I'd often let them know weeks I knew I was going to need a little more support, and plan lunches or afternoons together as distractions.
