This is not a metaphor
Last night, there was this strange feeling of lightness under my feet. It is as if a great weight has been lifted from my body. Is it that I have overcome challanges in my work and health, and is it that I have resolved some serious issues in my life? This light and giddy-headed feeling continues, and I look at my nailbeds. I examine them, and then I realize that the above may be the case, but it is also true that I'm not getting enough iron.
