Some folks run, refusing to face the possibilities. Me, well, I'm a born again coward, but life is full of risks so I'll go for the tests and figure any result short of death is a win.
But...that doesn't take away the fear and dread. And the longer you wait for answers, the greater the fear and dread. I also stress out more when I don't know what the process is. I really value technicians and medical personnel who explain every test in detail. I'm one of those people who like to maintain control, even if all that consists of is the illusion of knowing what to expect.
As you get older, you find your body fails in unexpected ways. Today I was supposed to give a urine sample at the lab. Except for whatever reason I couldn't pee! What the heck happened to the six glasses of water I drank prior to my appointment??? Fortunately, the technician handed me a plastic specimen cup with lid and suggested I take it home where I could work on my problem in private. I'm pleased to report I was peeing like a champ within an hour. Ah, life.
For all the folks out there like me who are facing the scary unknown, I offer hugs, understanding, and love. We'll make it through, one step at a time. No running needed.
