(First off, i usually don't lurk this forum; i'm BP, and a little borderline. But we all suffer depression at some point, some more then others. )

But holy moly... you too act like a chameleon to people. I thought I was the only one; but that too was, and still is, one of my major coping skills. (It becomes an extreme sometimes, but we won't get into that here.)

But it really depends on my mood, but for this forum, when i'm depressed I have the classic example of apathy in anything and everything. I had it bad this summer when I quit doing everything I once thought enjoyable; watching TV, watching anything, playing video games, reading... the only thing that kept me going was music. And only angry, or lifeless music like DJ cuts and noise/scream-electro.

Even to this day, when i'm depressed i loathe small talk, and prefer deep insightful chats about depressive subjects, and the psychology of others. (I have an immense interest in learning about other people's psych history, so i can best emulate them.)

But as a sufferer of BP, and depressive episodes, i can relate to complete and utter lost of interesting in all things.
