"I should be able to cope with this myself"
This is the belief that makes carrying it feel like strength. Other people tell. You cope. The difference is character.
I'd like to look at what carrying it consists of, hour by hour, because I think the picture of coping doesn't survive it.
Michael Slepian and colleagues, in 2017, studied secrecy in a way that changed how researchers think about it. The usual picture of a secret is a conversation in which you're hiding something, working to keep it out. Slepian's studies, ten of them, covering more than thirteen thousand secrets, found that this almost never happens. Situations that require you to actively conceal a secret are rare. What happens instead, constantly, is that your mind goes to the secret on its own. You're doing something else and it arrives. The researchers called this mind-wandering to the secret, and they found that people did it far more often than they ever had to conceal anything. Then they measured wellbeing. How often people had to conceal a secret didn't predict how they were doing. How often their mind wandered to it did. Independently of any hiding, the wander went with lower wellbeing, lower relationship satisfaction, less sense of being authentic, and worse physical health.
That's what carrying it is. It isn't a series of conversations skilfully managed. It's the letter in the drawer arriving in your head forty times a day, on the bus, in the meeting, at three in the morning. Nobody is asking you about the account. You're returning to it anyway, and each return is a small cost, and the returns are the carrying.
Now look at the word coping. Coping would be the worry getting smaller, or getting dealt with, or at least getting quieter. What the wander does is keep it exactly the same size and bring it round again. The person who's carried a worry alone for a month has coped with it in the sense that they've not told anyone. They haven't coped with it in the sense of being any better off than the day it arrived, and Slepian's data suggests they're worse.
Apply the standard you'd apply to a friend. A friend tells you they've carried a scan result alone for a fortnight so as not to bother anyone. Would you call that coping? You'd call it a fortnight they didn't need to have spent like that. Say it to yourself.
