"You don't know about... forget I said that. Wasn't supposed to interfere with that," Death stated, waving her wings dismissively. "Fact is, when you were taken from your world, nobody knew what happened to you. There was no body left behind. To the people of your world, you simply disappeared. Grim and I will arrange it so that you will return, your body as it was before, and your memories of Equestria will be taken away so you won't have to worry about anything. You'll be allowed to continue your life as you had before," she explained, basically stating you could go back to the norm. You could live again and not have to worry about feeling guilt for all the shit you did while you were here.
