Okay, so I did some digging and came across this - which might explain why you can't find it anywhere. The synopsis sounds about right and people mention Creepypasta Wiki in the reviews. So I searched there and found a story by the same name, but it didn't seem anything like what you were talking about. Some more googling brought me to this review which hits on some key points u/MattIntul mentioned in their post.

TL;DR - I'm 99.9% sure A Good Ending by Travis Kuhlman is what you're looking for!
