The heart aches, but the eye shed no tears.
This is the worse form of pain that can ever happen.

Because the pain that you've experienced before was so excruciating, your mind suppresses and stores it deep inside yourself. It stores those pain so deep that subconsciously, that part of your life has been erased from memory and you "forget" how that pain felt like.

You try so hard to remember that feeling, that pain again. But try as you may, you'll never succeed for the power of your mind knows no boundaries.

Because you've experienced so much pain, subsequently, nothing is ever considered painful enough. Nothing ever reaches your heart cause you'll already sealed it with a thick layer of cemented wall.

Then you start to wonder if there is a crack (no matter how small) between the thick layer of wall.

Congratulations if you've found that crack.

If not, you'll feel as if you are lacking something in your life. Everything feels incomplete. Time and place just goes past your eyes like frames of images. Not every frame is captured, and even less frames is processed.

Lastly, you'll start to wonder if you have really become the legendary cold, emotionless and heartless creature.

Oh, how you wish that your heart aches ever so often now.
