Hear that sound? You can't? I can. Every time I think about my son and what he's going through, the demons he fights because of his genetic heritage, I can hear the keening of my soul in despair. Every time I realize that my eldest may never be free of taking medication because of my genes, I can hear it. Every time I hear my baby daughter over the phone and know exactly what she is struggling with and she does not even know how to acknowledge it, it fills my head with agony.

What will become of my granddaughter? and what if my other children give me grandchildren - will they also fall victim to their parents' genetic weaknesses? I can't say it's unfair, but it hurts so bad.
