I'm on the hunt for some nice AU hurt/comfort, where Castiel has mental or physical disabilities, or is dealing with long term aftermath of an accident/illness/injury, akin to see no evil by zeppx (blind!pianist!Cas) or Sanctuary by Comedic Drama (agoraphobic!Cas)

Dean/Cas would be brilliant. The longer and plottier the better. My only concern is that it be a life long, or at least long term issue, and that the issues aren't the result of present abuse (I mean, panic disorders because of a bad childhood are okay, but injuries because of current boyfriend's munchausen by proxy aren't. ..does that make sense?) I'd like to see how the people in Cas' life learn/ have learned to cope with his condition.

Thanks so much!
