Life of a Depressed Wife

Hi you guys I'm married and I am a stay at home mom just until the kids go back to school my husband works 4 days a week (overnight) on his off days I still take care of the kids and house while he relax and go out sometimes I am really getting frustrated because I feel like I'm losing myself because I barely have time for myself Everytime I tell him how I feel he says he's gonna do better but never does I just don't know what else to do. Can you guys please give me some advice on how to handle this situation
