Depression

Depression is like trying to swim, but the darkness makes you blind. And the bricks attached to your feet only pulls you down. The pressure makes the air you have left in your lungs, slowly slip out between your lips.
And then you panic for a second, realising you are going to die. But then, you calm down, you find peace, realising that you'll soon be gone, and the drowning and suffering will end. Then your lips turn in to a smile, and your last breath of air slips away. It's gone. And so are you.
