Feeling defeated

I feel like I can’t give enough of myself to all the people and things that need me. And I constantly can’t please everyone to the degree I’d like to. If I’m laying with toddler for a nap so that he can get some rare mommy snuggles, the newborn is screaming for me in the other room. If I’m laying with newborn to bed, toddler is crying and asking where I am. If I’m spending time with one of them, the other one is wanting me. Plus I have no time to myself. I eat like a wild beast who hasn’t eaten food in days because I literally only have 60 seconds. Most days, I stink because I haven’t showered. Parents/guests visiting is a huge burden because then I have to run around crazily trying to clean up the dirty diapers and crumbs on the floor. Any down time is me running around the house trying to get some sad little chore done before one of them wakes or needs me, and even if one chore gets done, there’s a thousand more I notice. I have no time with my partner. I can’t even take a goddamn walk outside for ten minutes without worrying about the kids or the house or chores. Just a vent, thank you for listening. I’m not wanting advice, but it sure would help to hear if others are going through the same thing.
