For the mainstream it doesn't sound good when one hears a statement like, "I feel your pain." Maybe it would be better to say, "I can appreciate your pain." The reason I say so is that we all go through pain and want to sometimes connect with the ones feeling the pain. I believe that is what made Opray Winfrey so popular. Many don't realize what she has gone through.
I have worked as an emergency responder and have seen some pretty strong looking grown men cry for seemingly lesser looking injuries than a much more fragile elderly woman. Because of that it has opened my eyes to just care for the injured. Give them hope but be truthful at the same time.
Some believe that by modeling another person you can experience the same feelings as they are. If you think about it, a feeling, although it can hurt very badly, is actually a state of mind. Maybe a person can't understand truly why you are feeling such a pain because that person isn't you, but that person can feel pain just as you can.
