I wanna give up on pumping

I may be a sahm but I have no time. I let cleaning slip away one day and the house is destroyed. I need to pump at certain times and can't cause someone is crying or my other wants food or has to go potty 50 times a day or gets into something she's not supposed to. Or out running errands and they take too long. I'm stressed out really bad and idk what to do anymore. I don't want to put him in formula cause we can't afford it. My job screwed me over with maternity leave. I have to wait for an opening, someone gets fired or quits or the one girl has her baby, to go back. I'm pretty sure it's illegal with what they're doing. Not to mention they got bought out from another company and the new boss is a frickin idiot. My old boss retired unfortunately :( Pumping really takes up a lot of time I don't have.
