How do they do it?

 My husband has been out for four days now, and I just want to snooze for a whole month. Hats off to single parent homes.  Moms and dads who depend on no one to help raise and educate their kids, and do a great job. I admire their strength. But it's much more than tired nights and achy hands.  Small nuances: Lonely nights with a sick kid, no time to fix the lightbulb in the hallway, no one to make you feel safe,  the quiet and empty space next to you in bed.  Really, how do they do it, day in and day out? Again, hats off!
