song du jour moby.. why does my heart feel so sad?

I am feeling one of those lows that I know I am going to see myself through. I have a lot of stuff to get done today! Already accomplished a bunch today, just need to get some more stuff done. Life is getting back to a structure, trying to get myself together to make sure that I survive this adverse situation. My book is coming along well, I am trying to eat healthier and wipe my kitchen counter before going to bed. Somehow, the simple act of wiping the kitchen counter and closing the trash bag makes me feel like I am doing something to take control of my life and make it better. Its not exactly cathartic, but its comforting in its own way.

Why does my heart... feel so sad?
