I cried tears of relief when Andrea Yates was found not guilty by reason of insanity in the drowning deaths of her five children. As someone who has experienced mental illness, I felt gratitude for the jurors, who were able to recognize that she was clearly very sick when this tragedy occurred.

My satisfaction was quickly tempered by sadness, however, as I continued to follow coverage of the verdict. On one live cable news program, the hosts and audience shook their heads in disgusted disbelief as the verdict was announced.The featured pundit expressed anger that the insanity defense even exists.A quick review of blog commentary and the vitriol grew – many wish Yates had received the death penalty and would be happy to serve as executioner.One of the milder writers complained that Yates “had plenty of time to snap out of it.”

This made me physically shake. How could they be so smug?How dare the audience sit there looking as if they know everything, convinced that there obviously has been some huge mistake? How dare those bloggers sit in judgment of something they most likely knew nothing about?

I think it is because they believe that things they can’t imagine must not exist.They can’t imagine not being in control of their actions.They can’t imagine that the thinker might not be thinking the thoughts.It’s just not possible.

Unfortunately, I can imagine not being in control of my thoughts, as can many of you. We know it is possible, and it does happen.Nearly five years ago, when my first child was born, I suffered from postpartum obsessive compulsive disorder. I remember the exact moment the illness reared its ugly head.While burping my infant son one night, I suddenly had the thought “What if I smother him with the burp cloth?” There are no words to describe my terror and confusion at that moment.Can you imagine having a thought come into your mind as clear as a bell that is in your voice but isn’t yours? Most people can’t.

More thoughts followed over the coming weeks: “What if I drop him down the stairs?” “What if I drown him in the bathtub?” These thoughts were joined by the inability to eat or sleep, constant crying and the belief that I was not capable of being a mother.

I had never suffered from mental illness in my life prior to that time.I was a competent, educated and successful young woman.These things just didn’t happen to people like me.Wrong.The truth is everyone has the same capacity to experience what I did, or worse, what Andrea Yates did.You can sit there and shake your head, completely assured there’s not a chance in hell, but you do.

I was treated and recovered and am now the happy mother of two wonderful children.But my heart continues to break every time I see the suspicion of and ignorance about women with postpartum mood disorders.Many assume we are simply weak, defective or selfish.How can so many Americans show such a lack of compassion for the mentally ill?

Pete Earley, former Washington Post reporter and author of the fabulous book on mental illness called “Crazy”, helps me make some sense of it.In his book, he writes, “We lock up the mentally ill because they terrify us.We are afraid of them and even more frightened of what they symbolize.We want to believe they did something to cause their insanity … The federal government says mental illness is a chemical imbalance and not something … that anyone seeks or wants or deserves to get any more than he seeks, wants, or deserves to get a cold.But deep down, we really don’t want to believe that’s true.Because if we did, we would have to admit:It could happen to us.It could happen to me … And that is such a frightening thought that we quietly search for explanations to prove that the mentally ill really aren’t like us and they somehow deserve the torment they suffer.”

People would like to believe Yates was a devil rather than a normal person stricken with a terrible illness.They forget that all of this could have been avoided if society demanded better care of the mentally ill.Women need to be clearly educated during pregnancy about postpartum mood disorders.They need to be screened for symptoms after birth.We need trained doctors to treat them properly.We need to demand they not be released from the hospital if they’re a danger to themselves or others, regardless of stingy insurance companies.We must stop assuming they can just snap out of it.We owe it to the souls of those lost children.
