Very poorly Sammy

[josielouise]

There is a specific story I read ages ago. It was Sam really poorly with an undiagnosed illness. I remeber he was just getting worse and worse and the doctors didn't no what was happening. There was also a group of specialized doctors that look into hard to diagnose casses and eventually they did find out what it was but Sam was very, very ill.

Also is there any other stories with Sam with a harsh illness or disorder? Is there is epilepsy, cancer, brain tumor, Ptsd or anything were Dean is looking after Sam and Job band the rest of the hunters and really protective and worried about little Sammy. I prefer protective John and Dean and pre series.
Thank you for any help you can give.
