It Only Gets Better (Completed)

So, this is a short story that just popped into my head today. It's a bit sad in the beginning, but the ending depends on you. It depends on how you want it to end. I'm leaving it up to your imagination.
Warning: This is going to be slightly religious, so if you don't believe in an afterlife, don't read this story. If you read this story anyway, then don't leave hate in the comments. Thanks :)
Warning (Part 2): This may be triggering for some people. I apologize in advance if it is for you.
