“It is not that science is failing us. It is simply that the solution is as complex and multifaceted as the illness itself. For every theory of its causes, there is another to contradict it; for every new treatment, there is another that dismisses it as ineffective. This is not deliberate obstruction. Depressive illness, as well as being complex, is highly individual. What works for one person does not work for another. And often there is no explanation why this is so.”
