I went to bed early (for me) on Monday night. I had an early morning meeting the next day followed by an evening event. I knew that a long day was ahead of me, and I was patting myself on the back for trying my best to be rested. I had left my phone on, as I had promised Emily, because she was working a rare overnight shift. By 1:00 a.m. on Tuesday morning, she was texting me. “Mom, something is really wrong. I’m feeling so sick.”
