How do you find the time to eat, sleep, clean, etc. when taking care of a newborn?

My baby is 11 weeks old. I’m a first time mommy, so this is all new to me. I’m finding it hard to find the time to sleep when baby sleeps, clean my house, and cook dinner. Im exhausted, my house is disgusting most of the time, and we keep spending money eating out...which is also causing my baby gas.

I’m getting extremely overwhelmed and stressed about all of this. How do you find the time?
