Sinking

No matter what, no matter how I try to change my thinking, no matter how I look at things, no matter how hard I fight it, I feel myself pulled down yet again into a dark place. Now I know that any time free of this deep despair is a gift, because it does not last. And I find myself, as I find myself now, sinking. And at times like this I feel no one can help me. Friends are inevitably repelled; acquaintances would never suspect; loved ones are too scared. What do I do? What do I do? What do I do?
