Another option I often use is to have phone sessions with my therapist when I'm not well enough to drive 40 miles to see her or other obligations make it too stressful to fit in an appt. I find that even just 20-30 minutes on the phone with her helps. It's not the same, of course, as a full face-to-face session, but at least I'm getting professional support, advice, etc. It's often more like triage or damage control for the really bad times, as opposed to working on the underlying issues, which is more doable for me during better times.

I've also recently begun emailing her on crisis days, and that helps, too.

Perhaps your therapist would be amenable to these kinds of options? Especially at such a busy time for you.
