When my T talks about self-care, he means 'psychological' self-care which I feel is quite different to physical self-care.

Psychological self-care is looking after your own mental health. I see my T for three quarters of an hour each week and the rest of the time it is up to me to do the caring.

Sorry if I have gone off on a tangent here but to me self-care (said by a therapist) is meant in the therapeutic sense.

Take care.
