I'm like a...

If I need to describe how I am right now, I would say...

I'm standing at the edge of a cliff, and it would only take one horrible moment to shove me down.

I'm like a piece of paper, right next to a burning candle. And I can bursts into flame in a matter of seconds. 

I'm like a little cube of ice. Left out in the hot air. And I would disappear when you're not looking. 

I'm like a love song. The kind that you can hear all day when you're in love. But you would hate when you're not.

I'm like air. I can be seen but unseen.

I.A.
