Last year, my therapist was severely ill and out of commission for more than a month. It was a scary time. Fortunately, I didn't know how sick she was until she was fully recovered. If I had known how bad it was, I would have been a wreck.

A couple of things helped:

1) I spent some time thinking up a funny joke centered around her health. She was having surgery on her colon, so I made a joke about her guts. I slipped it in her door slot (lucky me, I know where she lives), but turns out she didn't get it because she was in the hospital. But when she came back to work, I emailed it to her. She loved it.

So you could make something and find some way to get it to her. (Like contacting a secretary, if she has one). The act of creating will be relaxing, and you'll also feel better doing something rather than worrying/ruminating.

2) I worked with a substitute therapist in the interim. It gave me a chance to compare my therapist to someone else, but it also made me feel connected to someone. She also allayed my worries about everything.

You will make it through this absence.
