Over the years I have learned that 1) almost anything reasonable is worth trying when I am down, anxious, lonely, whatever ... 2) I am frequently surprised by what ends up being helpful and 3) just when I feel like I am at the end of my rope and can't take myself anymore, something comes along that I did not expect and I feel better. I would put that call from your therapist in 'something unexpected' category. It might be her job to check on people, but I bet you are in her 'special' client category.
