She probably has anxiety and not an illness. I don't mean to sound rude but OCD's compulsions would lead to breakdowns, and it just doesn't happen with Twilight. Sure, she had a few breakdowns; Even those in good mental health can have breakdowns. Although, perfectionism or anxiety ≠ OCD. These are frequent misconceptions..

I know this was a long time ago but I HAD to reply. To those saying that OCD (if she even has it) is a "cute" trait of hers or is what makes up her entire personality, please STOP it. OCD is a real mental disorder that takes control of your life, it is nothing to fetishize. And while it can erode one's sense of identity, it's not who they are. As for my personal opinion on this matter (and as an individual who is very likely to have OCD), there is a difference between perfectionism and obsessive compulsion. Twilight seems to enjoy what she does and takes a liking into it. It seems to be perfectionism. I will add that OCD isn't fun. I don't think anyone with OCD takes a liking to their compulsions. The things Twilight supposedly places perfectly are just placed with a single try, she does not have checking compulsions over symmetry or anything like that. If you're going to tell me "Well, when she moved out of the castle, she checked the rooms a lot", that's the stress of moving out. We know how Twilight get, but it doesn't necessarily equal to OCD.
