Specific Dean death!fic search + deleted user request

[cheeseontoast1]

Hi, so I'm looking for a specific fic that I remember reading quite a while back. Dean is praying to Cas but Cas isn't able to answer or to help him (might have been set in Purgatory?) Eventually, Cas is forced to listen to Dean die (from blood loss iirc). Loved it, desperate to be reunited, please help.

Secondly, does anyone know what happened to onefulloctave and if they are happy to have their fics shared? If so, please let me know if you have any copies. I loved so many of their fics, was so sad to see them go!
