One of the best things that you can do is bring up memories you had together, the good and the hilarious ones because that subject always brings joy and laughter. Laugh things off to clear out the gloomy atmosphere (it’s healthy for you and the dying person).
Keep in mind that when you are witnessing the very last moments of someone’s life, they will go unconscious, don’t panic and don’t overthink it because it’s a natural process, the best thing that you can do is to continue talking, singing, or telling the joke you were telling them because, according to science, hearing is the last sense that shuts down.
If you notice bruising on the skin that starts popping off all of a sudden or a change in breathing patterns, don’t panic and don’t be scared because those are natural physical symptoms of dying.
In the end, there’s nothing to predict, just flow with the situation, be fluid, gentle, and flexible because no matter what you read, no matter what you watch, nothing can prepare you for that moment. The only things that you can control are your actions, so make sure to show as much as you can, share as many thoughts as possible, and most importantly, make the dying feel loved, appreciated, and wanted.
