Feeling unappreciated and burnt out as a 40F mom

I have been a stay-at-home mom for the past 15 years and I love my kids more than anything, but I can't help but feel overwhelmed and unappreciated. My husband works long hours and when he gets home, he expects dinner to be on the table and for me to handle all of the household chores. I feel like I am constantly running on empty and never have any time for myself. I'm tired of feeling like I'm not good enough and like my contributions to the family are not valued. I just need to vent and get this off my chest.
