I use to do a little journal when my therapist went on vacation, specifically for that period of time (used the tiny "blue books" you get at college to do exams in:

That's hard with your husband going away too. I've had that happen. Especially important to think/write about what you're thinking, feeling, working on while all that's happening so you can share it with your T when he gets back.
