Looking for a story that was not on deviantart, dailydiapers, adisc, or abdlstoryforum. It was about a girl getting sent to an diaper asylum against her will and meets a female friend, and the protagonist ends up staying by choice. Given that description and not being on common abdl story sites I realize it's not going to be easy to find.
