When in the dark days, I did nothing for myself. I am a single mom and was struggling financially at that time. Especially with all the added costs for therapist, medications, etc. Now and then I would go out with the girls & I did have every other weekend free when she went to dad's. But, I really did not recharge at all. I was always on edge and worried even when she was not with me.
It was later that I realized just how important taking some time for yourself really is. Massages, pediures, manicures, etc. all cost money - which I am fortunate to be able to do now, but only once in a while. It is just different when they are older. I wish I knew more when it was really bad.
