As my youth catches up with me, invoicing me for my poor decisions, I encounter the tendency to start dreading this or that now rather than wait.

While I might perhaps be avoiding long lines, I have to fight that. It would not do myself any favors.

I think some of us are more keenly affected by surprise than others. At the dentist, I ask her to let me know when we are a quarter of the way through, halfway, three-quarters, and nearly done. (I have a marvelously compassionate dentist.) If I’m having a medical exam, I must rassle my mind away from predicting all the possible batches of very bad news. Telling me my A1C needs to come down thus seems bearable, given that I was preparing to hear they were concerned about some mass in my abdomen.

Earlier this month my wife and I celebrated the twenty-fifth anniversary of her acceptance of my marriage proposal. We might be the only couple out there who celebrate such a day, but that’s all right with us. The fact that we’re having one, and that the only thing that will prevent a twenty-sixth is if one of us has something sudden happen to him or her, speaks for itself. Celebrate a day, again and again for a quarter century, and one communicates that one remains grateful for it.

Something sudden is the problem. If not restrained, my mind is sort of like a cat. Now and then it will wander off into someplace that doesn’t help anyone, and this would become paranoia if not handled in a sane fashion. For me, that means refraining from pre-suffering. It’s one thing to grieve ahead of time for a friend lost to pancreatic cancer–something I recently did–because it’s not paranoid to imagine that the friend will not survive it. Few do. It’s another thing to take that ball, run with it, and start thinking about a day in the future when one or one’s spouse might be given news of such a deadly affliction. And then to start processing grief on some level.

That’s pre-suffering, and it helps no one. It also carries with it a terrible pessimism, and this also must be battled. Imagine I were to find myself a sudden widower. If I’d worried myself half to death about that possibility for two decades, would the pre-suffering and all the time it had ruined do one bit of good to help me once the real thing was present and undeniable? I don’t think so. We have no idea how we will react to close loss, regardless of what we imagine. If I were eighty-five and received a diagnosis of dementia, would I grieve less if I’d screwed around for the last twenty-five years fearing dementia? Bet most people would not.

In essence, pre-suffering is an investment in an emotional stock that looks on the surface to be a huge bargain but in fact is going to zero. It is the Thornburg Mortgage of mental attitudes. (Let’s not talk about why that analogy rings so true for me.)
