Feeling unappreciated and overwhelmed as a mom

I (40F, mom) have been feeling really unappreciated and overwhelmed lately. My kids are 10 and 12, and they seem to expect me to do everything for them. I work full time and come home to a messy house, hungry kids, and a never-ending pile of laundry. I feel like I'm constantly running on empty and never have any time for myself. I've tried talking to my partner about it, but they just tell me to take some me-time, which is easier said than done. I'm tired of feeling like a maid and a servant. I love my kids, but I need some help and appreciation.
