Nah, that’s the thing with mental disorders and other things: They’re usually just an imbalance of otherwise normal behaviors/moods/etc. Most people should be able to relate to most mental disorders.
They just shouldn’t do the, “lol I’m so OCD!” thing, because that trivializes how nasty the real disorders get. The people with the disorders don’t just have flashes of silly desires or emotions (usually), but rather a literally debilitating to normal daily life disorder that no one would want to deal with.
