Don't fear that. Psych wards are for people who are in immediate danger, and the only way to save them from themselves is to lock them up under constant medical supervision. A meeting set up with a doctor, where you lay out your feelings in a rational manner, and justify your cravings...it gets met differently. If you calmly and rationally explain to a doctor you want to die, they can't commit you, because you are not being unreasonable or showing signs of panic. They need a reason to commit you. Just wanting to die, isn't enough, you need to show major instability for them to get legal backing in throwing you in a ward. If you come at them calm, cool, and collected, they have no legal ability to commit you to a psyche ward.
