Interesting article. I was in a similar situation a few months ago. I won’t go into the boring details, but I received some good counsel that told me that it’s okay, in fact necessary and important to take care of myself. I am in a quasi caregiver situation on top of many other demands. If I am not taking care of myself, then I won’t be any good for anyone in my care. Plus it’s okay to take care of yourself, just for yourself.
I would expand the concept to include adequate rest, proper nutrition, exercise, and spiritual and emotional rejuvenation. It’s helped me move away from the edge of completelly falling apart.
