I see a lot of depressing comments here. And to be honest they are relatable. But the thing is that they most likely describe the personification of existence. Life is not suffering, no matter how miserable you are. But existence is, of course, suffering.
But everyone lives in different places with different people, so it’s probably impossible to name the exact personification of existence itself. Everyone has their own view of existence.
I would describe life as something positive. When a person is depressed and he sits in his room not wanting to do anything, then he simply exists. At this moment he is not full of life. Therefore, life is something happy and cheerful, and existence is both joy and sadness.
