So, looking for something specific. I remember it was a fill on one of the memes, probably glee angst, but I've looked through a few hundred pages of comments and can't seem to find it anywhere. In the fic, Kurt hurts himself during glee practice, and the whole club goes to the hospital with him. The doctors give Kurt some pain medication, and he gets all loopy and talkative. At first, he's blurting out funny things (says something to the effect that he expects birds to come flying out of Mr. Schue's hair) but then he gets serious and tells everyone how terrible the bullying is and about previous times he's been in the hospital because he was attacked, and once when he tried to commit suicide. He doesn't realize what he's saying, but everyone else gets very sober and promise they'll be better friends in the future.
Thanks for your help!
