How to feel miserable.

Maybe subconsciously, I want to give up, as much as I think I am contented enough. But sometimes it just gets so dreary, it had to go way beyond the threshold and I know I have to scream at someone. It's annoying really, how everything gets so uninspiring. Or maybe it's me. Perhaps I've been kidding myself all along and continued the pretence till even when the curtain had long gone down.
