Being a caretaker is exhausting work, on many levels. I read some where that the care taker will usually give out before the patient. Even more reason to spend some time to repair thy self in however that works for you. But being a caretaker seems to be a lot of our make up and probably why we are such great targets for the disappointment and self doubt. I also read in book where "To be loved, you must know love" "To be happy, you must know happiness" it applies to all kinds of things such as respect and care.
