Where do I take this pain of mine

Pain. It's the one thing we all loath, but the one of the many things we can't live without. The purpose of pain, according to most studies, is to warn you that your of potential damage. Stepping on a nail is definitely a good way to damage your feet, so you body needs to teach you the hard way to watch where you step. Pain itself, contrary to what you may think doesn't harm. Although harm or potential harm will cause pain; It isn't pain itself that deteriorates your body; instead, just your mind.

That's how you learn. You know that pain wears you out, and so your mind establishes pain as a negative feeling, a sensation to be avoided. This means you'll not harm yourself.

So then, what in the world is emotional pain. I'm quite (damn near 100%) sure that the heart has nothing to do with anything other than pumping blood. The whole reference to the heart; the phrase "listen to your heart" is purely metaphorical. The rate at which your heart beats is influenced by hormones, stimulated by parts of your brain.

I think it's a social thing to feel loss over something or someone. That's why pain is so relative and subjective.
