Put another way, apathy for me is usually a form of denial or numbness, either I'm pretending to not care or I'm worn out from caring but still care enough to keep the worn out feeling going. Now it's like I literally don't care one way or another anymore. Lately when I think about my situation, and how I should be doing more to fix it, it's with a detached sort of "Hmm, I should be doing such-and-such." I still can't get the energy or willpower to do these things, but it feels different now. Where before it had a note of depression to it, now it's as though I'm thinking about something completely unimportant. Like you might feel if you saw a piece of paper on the ground outside; you might momentarily think, "Oh, I should pick that up," but you don't, saying to yourself, "Nah, it's too far away; besides, it's bio-degradeable." The thoughts about my situation and how my life is going now feel like they have no more importance to me than considering picking up a piece of litter.
Thinking back, I don't think I've ever felt this way before. I think this is my first experience with true apathy.
