Why does being a neurological condition preclude them from being a mental illness? I suffer from suicidal depression. Do you believe that's a mental illness? Before treatment, when I woke up in the morning, I didn't say "My serotonin paths don't feel right." I would think "Should today be the day I'll kill myself?" I am very fortunate that the cause of my mental illness is easily treated; the SSRI that I take started working almost immediately. The serotonin paths in my brain appear to be defective. That's neurological, right? https://en.wikipedia.org/wiki/Mental_disorder https://en.wikipedia.org/wiki/Mental_disorder
