This Isn’t Expected...

I’m plagued by the question of what happens to the undead if they, assuming "they" had a consciousness, decided to commit suicide? Can they die? If the undead die, where do they go? The living already have guessed where they may potentially end up. Do the undead go to the same place? Do they have a special undead land they arrive at once they choose to die? Do they have an undead hell? What is undead heaven like? This is why I don’t share my thoughts.
