your family.
Change it. Derive your self worth by maintaining that "self."
Slaving yourself after them ensures their treatment of you as a slave. Your children's attitude toward you came from their father.
Remind the children what to do and when, everyday but only once. Tell them that actions (and inactions) have consequences. Do not clean up after them (you are encouraging their behavior by cleaning up after them.)
Use the time and energy to pamper yourself, mentally and physically. And do it conspicuously.
Love yourself more. That is YOUR duty, not theirs. When you love yourself, others will follow. People treat you the way you treat yourself.
A cleaner home might just be a by-product.
