I’m just so miserable

My children are 5,3,2 and I am absolutely miserable. I just returned to working full time and it saved my life. My children cry and whine and scream all day every day. The second we get home from school/daycare. On the weekends too. It’s non stop. My husband is miserable too. It doesn’t matter what activities we have or or positive we are it all ends the same. Them screaming at us, us just ignoring them. I absolutely hate it, sometimes I even feel like I hate my life. Mostly y because I feel like there is something wrong with us- does anyone else’s children act this way? Im just so upset and don’t know what to do
