In our lifetimes, we all run the risk of a corner of our hearts turning cold. It usually happens when fear keeps us from expressing ourselves, or some event hurts us emotionally, and the only way we think we can survive is to freeze sections of our hearts. The human heart can only hold so much pain before it reacts.
Fear is usually the beginning of the freeze of the human heart.
It never goes away by suppressing it. The only way Fear goes away is by recognizing it for what it is, and by talking about it. Talking freely about it. Open dialogue can erase human fear. In the world we can try to control human emotions, but the problem is, human emotions cannot be changed by governments, or suppression, or individual groups.
