There are many reasons people die by suicide when living with mental illness, but I’m going to focus on three. Suicide is an all-too-common outcome of mental illness, and most suicides have untreated mental illness as a factor. But what drives a person to the edge? What overrides the instinct for self-preservation and causes a person to end it all? I’ve attempted suicide, and these three reasons people die by suicide hit closest to home for me.
