Emotional pain, or physical pain?
Sometimes emotional pain can be so deep, it takes on physical forms.
Fear, pain, and anger can tear a person apart from the inside. Let it go... and if you can't do it alone, let your family and/or friends know.
Pain is part of the human condition, but it is not a positive place to be. The challange is to rise above it... to change it and yourself... to embrace a better you... to make a better world. :)
