Even though children themselves never think of death, and you probably avoid the thought of it too, just take a moment and imagine yourself on your own deathbed. Doing so will also help you bring total peace to any situation you are in that is causing you anxiety. When I myself worked in a hospital, I would often have patients in the ICU (intensive care unit) that would tell me in a similar way what Mark Twain wrote over a hundred years ago: “I have known a great many problems, and none of them ever happened.”
People that I spoke to who were dying were so radiant and peaceful. I am sure some of them were anxious about dying, but once the acceptance of the inevitable happened, a calmness came over them. They knew what was important. You can research it on Google or ask hospital nurses you know. The old saying that nobody on their deathbed says, “I wish I spent more time at the office” is absolutely true. Nobody wishes that they would have made more money, or gotten that promotion. All they want to talk about is their family, thoughts on God, maybe pain that their bodies are still having, and such. But they never discussed things that made them miserable beforehand, like remembering a time when their ex-boss fired them for something that wasn’t their fault, or a regret about a career decision, or a painful bankruptcy filing, and so forth.
So try this exercise as daily. At least once a day, picture yourself on your deathbed about to go on away from this world. Think about what nonsense it is that you currently fretting over. All the nonsense and “things of this world”, like comparison, lost ambitions, your expanding waistline, past painful incidents will all be a non-issue. Doing this exercise will further prove to yourself that your problems and pains are really all in your own mind.
The only things that truly ARE real are the present moment experiences, and those that are giving you trouble can be realized as a fiction if you expand your awareness to this moment to being on your deathbed. However, if you are, in your present moment, feeling real physical pain, then I would have to agree that that is real and needs to be addressed. But real physical pain can be alleviated in today’s medical world. What reeks continuously is your psychological pains that you carry over and over, which in my opinion are far more aggravating than the headache you may experience during say a menstrual cycle which can be quickly fixed by an aspirin tablet.
