kidnapped!dean, john goes insane and abducts dean

[caramelzip5]

I read this fic ages ago and I can't find it anywhere with google searches. Basically it's an AU where monsters don't exist, but John goes insane and starts thinking that everyone is a demon (I think he has a brain tumour/schizophrenia or something). He takes Dean and drives off in the impala, and the story is sort of like a diary of Dean's life on
