Humans are like a canvas,
Filled with vibrant different colors full of beautiful emotions, and different variety of shades.
Of course, a canvas would be incomplete without light.
But remember, without a light is without a shadow.
The two coexist to make the canvas complete. Which is why, humans cannot be without dark. As darkness is there with light, which makes us whole and complete the way we are.
There is nothing to be ashamed of feeling dark and gloomy. Because that, is what makes us perfect the way we were made to be, as well as the flaws that add flavor to our every person.
