How can that be, after a shot? No real sleep for me now. What to do? Wait, check again in 30 minutes? Page the on-call diabetes doctor? I just want him to be okay, want to sleep. A full day of work awaits, arrives in less than six hours; I need to be at my best. Not exhausted and struggling for coherent thought. Even worse, the few ways in which I can help my son aren’t working. Despair surrounds me. I cannot give into it. I must figure this out.
