I can be in a horrid mood one minute, then laughing my ass off the next. And then back to the dark side yet again. I'm guessing this is common for most NF's. Maybe just F's in general. Also, I have noticed that if I listen to certain kinds of music it will put me in a better or worse mood. I rememeber being able to listen to anything, at any time, and still keep my mood. Lately, my mood has simply been a product of my environment and I am tired of it. Obviously depression is in the works, but it seems the older I get the more everything affects me.
