Hover:

An intransitive verb

to waver
As between life and death. Between numbers that show increased and then diminished red blood cells. The equation never balancing out. Always faltering between where it should be and far worse.

to linger uncertainly in a nervous or solicitous way
I lay in the floor next to him, observing the rise and fall of his breath. I touch his fur lightly and feel his warmth. I watch how he moves, looking always for his untroubled agility, light steps, inherent feline grace. I study his eyes. I note the color of his tongue, how much he eats, his insatiable thirst because of the steroids. The near constant scrutiny exhausts me and makes me restless.

to remain suspended over a place or object
Holding in the heartbreak most of the time until it ekes out, slides down my face, trembles on the edge of my chin, holding until the salted weight is too much.

to move to and fro near a place
We shuttle back and forth between home and the hospital. Work and the hospital. The waiting room and the exam room. The ICU and the outpatient services. The ongoing rotation of doctors and residents and students who carry the thickening file from the front desk to the discharge desk.

We drive back and forth between my parents' house and my house. We move furniture, small boxes and mow the lawn. We flutter through the rooms briefly and then depart, leaving a hollow echoing shell.

to hang, fluttering in the air or on the wing without moving in any direction
At times in this endless free-fall, I force myself to stop thinking about any of it - the lack of answers, the mounting expenses, the mortgage I'm paying on a house I don't inhabit - and I coast. I gather him in my arms and hold him so that I can absorb his breath, his heartbeat, his purr, his sleek black fur. I hold him and we stay there in that moment with no yesterday and no thought of tomorrow. Only warm, weightless safety.

to fluctuate around a given point
Life is driven by Kudzu. The times we must administer his medication. Leaving work every evening and coming directly home-do-not-pass-go to spend time with him. Fitting myself in the spaces where he lays - by the water bowl, snugged up to the vacuum cleaner, on the old coffee table in the spare room. Bending myself into the small spaces just to be close to where he is.

to be in a state of uncertainty, irresolution or suspense
No one knows why but suggests the answer may lie in the bone marrow, that deepest place where we have looked before and found nothing. The doctors want to invade again and look for those terrifying diseases that will give a name to what is sapping his strength. But I'm not sure that I can. I'm not sure that I can put him or me through that.

We go to the doctor again on Tuesday to check his red blood cell counts. And they will give me too little information and want me to make something of it. To decide what to do next. Which gamble should I take? And does it matter, when I feel like, in the end, that death holds all the cards? My next play is a faceless card, gripped tightly, being pushed toward the table with fear, hovering there, unable to let it fall and finish the game.
