I have a history of worrying myself to the point of illness. Recently, I've noticed that this helps. Does this help for you too? Or am I just an idiosyncratic nutcase.
Whenever I'm feeling stressed or overwhelmed, or am on bad terms with my inner demons, I do this: I close my eyes. And remember the ceiling. I picture myself, where I'm sitting, remembering the ceiling.
I don't know why the ceiling helps. But when I think of it, I start remembering things. I remember that I'm a lone human being, in a house, on a continent, on a world in a universe of infinite others.
My problem, in my head, starts to become stated as fact.
It's not "Ohmigod-I'm-going-to-fail-this-test-I'm-DOOOMED!!!"
It's "I'm sitting here, in this room: a teenager that forgot to study. The test is soon. I'll write it. The marks of a lone test won't matter in the long run. It's not the end of the world, or at least mine. I'll surive."
Am I making any sense?
