How did sadness become so familiar I can almost hear it chanting my name

Sadness… It is more like melancholia which I believe I was born with. I was eight years old sitting on a breakwater that my father had fashioned to protect the dikes from the waves when I first realized that this world has nothing to offer to me. Even then the feeling of being been there done that twice over and back was prominent and constant. I was not sad nor depressed. Just an understanding of a fact. There are only two occasions in my whole life that I’ve felt that way. For the rest, I’m fairly okay. Melancholic but never lonely.
