You've done great in taking care of yourself already! You'll be okay.
Days like this make you feel like you are taking one step forward (arranging daycare this summer)
and two steps back (sick child and absent parent).
It's all good!
It's part of the growth process.
I think it is Melody Beattie that describes growth in a circular swirling pattern (oh, what's the word...) like a tornado cyclone - the swirl is pushed forward by the slight backward rotation.
You just propelled yourself farther ahead!
Keep on keepin on!
