Can you see another therapist while she is gone? I've done that a number of times before when my therapist felt I was too unstable to miss a session. There's another therapist in the practice who has some background on me and who can treat me if mine is away or something happens that keeps him out of the office. Usually we just chat a bit but it helps keep me safe and someone is checking in on me. We don't do it every year but if my therapist is concerned then he will set it up.
