Everything becomes unbearablely painful during heartbreak. You cry yourself to sleep, hot tears streaming down your face. Your tears freeze over. You awake, often jolted for some strange reason to a profound sense of loneliness.
You cannot eat. You cannot drink.
You become destructively and hopelessly foolish. You lose the ability to reason, you fall out of touch with reality, and altogether struggle to function. There is not enough comfort or substance in the world that can soothe the pain.
You watch yourself wither away. The thought of death becomes entirely pleasant next to the prospect of living through the heartbreak.
