This story ["The Depressed Person"] was the most painful thing I ever wrote. It's about narcissism, which is a part of depression. The character has traits of myself. I really lost friends while writing on that story, I became ugly and unhappy and just yelled at people. The cruel thing with depression is that it's such a self-centered illness - Dostoevsky shows that pretty good in his "Notes from Underground". The depression is painful, you're sapped/consumed by yourself; the worse the depression, the more you just think about yourself and the stranger and repellent you appear to others.
My worst character flaw that I'm conscious of is that I tend to think my way into circles instead of resolving anything. It's paralyzing and boring for people around me.
We all suffer alone in the real world. True empathy's impossible. But if a piece of fiction can alow us imaginatively to identify with a character's pain, we might then also more easily conceive of others identifying with their own. This is nourishing, redemptive; we become less alone inside. It might just be that simple.
If you're writing fiction, you're dealing with characters who, themselves, will have heartfelt sentiments but who, themselves, live in this culture right now and thus face all the impediments to sort of dealing with those parts of their lives that, you know, that we did. So it would be not only silly but unrealistic to have a character saying that kind of stuff.
If some people read my fiction and see it as fundamentally about philosophical ideas, what it probably means is that these are pieces where the characters are not as alive and interesting as I meant them to be.
I tend to think of fiction as being mainly about characters and human beings and inner experience, whereas essays can be much more expository and didactic and more about subjects or ideas.
