No one to share the worrying

I've been a single mom the last two days while Michael has been in NYC, and the hardest part isn't the physical strain of caring for two little kids-- you can hire someone or call on friends to help with that.  For real single parents, the hardest part has got to be the worrying.  Henry's still not completely over his mystery illness, and it ebbs and flows enough that I can't decide whether to take him to the doctor or not.  I keep thinking it is improving, and then it seems worse again, and I can't decide what to do.  And there's always Agatha's digestion to worry about.  I'm not really a worrier, but with just me here there's no one who knows the kids and cares about them as much as me.  Dealing alone with the constant, low-level anxiety of being a parent would have to be the hardest part of single parenting.  I'm glad it's only temporary for me!
