As you move through your life understand the majority of the people you encounter are experiencing psychological pain of some sort or another. Whether dealing with the death of a loved one, depression, alcohol or drug abuse, anorexia, obesity, personal rejection, a family member in dire straights, (ad infinitum) people hurt. They also exert tremendous energy masquerading as though nothing at all is wrong. It wouldn't fit the self-image they wish to portray; ie 'I've got it together.' One example of this being true is what people say when the mental pain becomes overwhelming: "I feel like I'm falling apart."
Don't misunderstand, I am not asking you to be your brothers keeper. I'm not asking that you coddle. I just ask that you become aware. That you extend your vision beyond yourself. Perhaps empathy is your response. Or, you may simply shrug your shoulders. Whatever you decide will be best for you. I realize that your hurt may run so deep there isn't room for anyone else's.
