Most people's comments have been a list of body parts they do & don't like, with some history (the parts that used to be thin) and future ambitions (I should really exercise/diet). Plus a few fantasies (taller, tail). There was general unhappiness with aging "so far", but little specificity in the worries of further aging.

You could try telling stories about parts of your body. (I tried this, starting with the toes. I feel pretty good about those, but things got more negative as I went upward. I gave up at the knees.)

Might be good to list all the positive things people have told you about your body or its parts.

In my experience, the unspeakable aspects of the body are the most important. Can you express yourself in media other than words?
