Mountains existed before your problem and will likely remain after it.

There is a specific relief in something that predates you and will outlast you. The mountain was there through everyone else’s worst year too, and it registered none of them. Your problem is real and it is also not the size it feels from inside, and standing under something ancient is one of the few things that reliably restores the proportion.

When a worry has grown to fill your whole head, get near something large and old. Water, rock, sky, a very old tree. It solves nothing and it puts you back at your actual size, which is often enough to think clearly again.
