Some of the deepest hurts are mental and emotional. These hurts will cause your thinking to change. We can't help that someone chose to hurt us. Sometimes it's so unexpected and it knocks us off our feet. However, our healing is our responsibility and healing of the mind is the beginning for everything else to heal in our lives. Like a said before, as soon as a negative thought pops up you cut it off and say a positive thought or scripture instead. The more you say it the more you will believe it and the more you will think it.
