Congratulations, you've died!
That's completely normal and healthy. Most of all, it's okay. With your death behind you, you'll be transferred to one of many Second Worlds across the multiverse. Each Second World is only populated by people who have already died before. For the sake of your enjoyment, you can use the whole knowledge of your past life to fully create the exact person you want to be this time around.
Once you reach your Second World, you'll be reborn as an infant, and you won't be able to remember your past life at first. This is to give you a healthy time to learn about the new world around you and get acclimated. But, upon your seventh birthday, all of those memories will come flooding back. It'll feel like a lot at first, but everyone in a Second World has experienced the same thing. You'll have plenty of support around you.
We hope you enjoy your second chance. There won't be a third one.
