My Thoughts.

To fall in love is to lose yourself; your mind, your body, your soul, and find it somewhere else. It's impossible to do if you aren't capable of doing so.
You may care, so much that you think you have gone insane. That you would jump of a cliff into a burning pit, and keep going. But love? Impossible. Until you are shown that you can be loved, that someone can both lose and find themselves in you, you may never know how it feels. And who would be crazy enough to do such a thing? To love the unloving, unlovable. No one, unless they themselves are already insane.
