It takes a migraine to clear my head

I was trying so hard to breathe deeply, to release, to let the fearful thoughts in my head dissipate. Yesterday morning, I took my boy to preschool on my way to two doctor's appointments where I was hoping to find out why I've been having chronic migraines for a month and over the last few days, tingling that spreads across my scalp to my face.
I was hoping to get some answers but also afraid that I'd need an MRI or hear some kind of concern or urgency laced in my doctor's voice. I could rationalize migraines, even one after another, as being the logical child of stress and not enough sleep and eating Luna Bars for two meals a day. But the tingling took me right to the brain tumor place and the brain tumor place is only milliseconds away from the frantic-ness of "if something happens to me, who will raise Lil E?"
Of course, I know who will raise Lil E if something (touch wood) happens to me and this is neither calming nor comforting nor OK with me. So I said some om namah shivayas, went to bed earlier and slept away as much of that worry as I could. I woke up feeling better and went about the business of packing lunch and putting on Diego undies (the boy's) and Mardi Gras beads (also the boy's), smoothed on berry red lipstick (yes, mine) with some silly thought that if I looked bright-eyed and big-smiled there could be no possible way a pins-and-needles-inducing brain tumor was growing in my head.
On the way to preschool, the normalcy of my day helped ease my mind. Lil E and I talked at length about the construction vehicles in the lane next to us and sang along to songs on the radio. There's something about an almost-four-year old in Sponge Bob sunglasses and a pulled-low baseball cap singing "No air! NO AIIIIIIRRRR!" to soothe a mama's worries about life beyond that moment in time, that note hanging in the air.
That moment turned quickly and I saw a familiar expression come across Lil E's face as I peered back through the rear view mirror.
"Mommy," he groaned. "Mommy, my belly feels sick."
