Stopping her little prowl around the void, Death looked down at you, emanating some level of sorrow and pity. "The other option is... I send you back to Equestria," she answered. You were totally confused for a moment, not understanding how both options didn't really seem to include any actual death, especially since you were already told you had flat out died. Seeing this, Death elaborated. "You asked earlier if you were dead. I told you yes and no. Your body is currently hanging on the very last strand of life, not giving up just yet. The only thing keeping you alive really is... well, you. The fact that you haven't totally accepted the fact you're dead yet. I can say what I will of you, but you're a fairly stubborn one."
