Feeling like crying....

I feel like crying, and I really do not know why. I could almost say it's like a storm inside me, but it's not that. Not quite. I just...wish I could disappear. Hide, fade...let everyone forget that I exist.  I could almost call it depression, but it isn't quite that either. I feel sort of wistful and restless. If I were an animal, I think I'd be curled up in hibernation mode right about now. It feels like I'm waiting, with no idea what I'm waiting on. I know, I know, it sounds weird to me, too. Huh. How the hell do I even begin to figure this out?
