How do you do it?

I SAH, and we live in a new town where we don't know anyone or have family nearby. DH absolutely has to be at work today for a huge meeting. I have a 5 week old and a 23 month old, who's already going a little bit stir crazy - we've been almost endlessly inside avoiding germs because of the newborn and avoiding frostbite because DUDE it's 4 degrees outside.

Anyway, I have mastitis, thrush, or something... a super painful breast, chills, just feeling like I have the flu. I'm trying to nurse through it and just taking the Rx ibuprofen I have leftover from L&D. I've sequestered all of us in my bedroom with PBS and Peppa Pig on the DVR, lots of toys and books for the toddler, and cereal, water, and coffee for me (newborn was also up every 2 hours overnight, which I guess is good for draining the breast but OMG can a person die from sleep deprivation?)

Any tips for lasting the day? I'm worried
