The need for sleep is biological, just like the instinct to survive, but the instinct to survive is a much older much stronger biological program, so it is much harder to override than the need for sleep. But a need for sleep and a need to survive both are biological programs. Wanting to die is not. If you want to override a biological program you will be met with resistance, especially if it involves overriding the need to survive because that is one of the oldest and most basic of instincts going back to the dawn of life.

Of course failure will happen. But that doesn't mean a person doesn't actually want to die. They do, they are simply incapable of overriding the primal program. Or they tried and the method somehow failed which is out of their control.

One of our many traits as humans is endurance. People have survived falls from high places and gunshots to the head. Furthermore, statistically, only about 10% of real attempts at suicide actually succeed (I'm talking about attempts that involve the individual going through with the action, not just hanging onto the edge of a high place, but actually jumping for example).
