Welcome to the Westphall multiverse
Tsukino Usagi as she lives in the mind of Tommy Westphall.
Tommy Westphall was an autistic character from St. Elsewhere. AIn the series finale it is revealed that the entire series was possibly a product of Tommy's mind - and as a result, any show that crossed over with St. Elsewhere was also a figment of Tommy's imagination. Enter the Tommy Westphall multiverse theory, where the core universe that exists in Tommy's mind contains no less than 282 interconnected, crossed-over television shows through direct and in direct reference - the assumption being that everything referenced exists in this person's mind. Keep in mind this is only the core universe of only TV shows and does not take into account comics, video games, movies, and the like, as seen here. If we counted the comics, books, etc. of these TV shows, the sheer number of interconnected realities in the Westphall multiverse (since some of the shows presented does reveal the possibility of alternate universes, i.e. Joss Whedon and J.J. Abramss works as just two prime examples of this) is actually very staggering and would contain most American comics ever produced, most major video games ever produced, and countless derivative works around the world.
So where does Sailor Moon fit into this equation? It's thanks to the inclusion of The Adventures of Superman and Batman. While neither show is not an 'official' canon alternate universe of DC, it is only not 'official' in that it is not a comic. But this show is an alternate universe - and hence a part of Superman mythos as well as the core Westphall TV universe and its potential offshoots. So, as a result, Superman and it's various alternate universes are practically included, as well as all characters in DC in connection.
The connection: Batman in one comic issue had a brief meeting with Martian Manhunter, who took on the form of a reporter named named Rei Hino, who is very clearly an alternate version of Rei Hino/Sailor Mars. Not only this, but Bruce Wayne seems to imply that he knows, at the least, that the character name is implicitly tied to Mars, which only makes sense if the character knew that Rei was from Mars (which we have to assume that Martian Manhunter did). With that theory in mind, Batman's metaverse is now connected to the Sailor Moon metaverse - and thus to its alternate universes and retcons. And so, Usagi is a part of Westphall's mind and the minds of those who have shaped Westphall's reality since, albeit not in the core TV universe - but she's there.
So.
In this particular case, this is to assume Westphall's entire multiverse is fictional. Usagi knows she's fictional and that she has been retconned many times (in the order of manga, anime and it's international dubs, SeraMyu, and now PGSM). She figured out the truth after she blew the world up in Act 49 - the power used to kill and then revive the world opened her mind up in death to the horrific, staggering truth of hers and everyone else's reality - thaty she was a character who's caught in a cycle of life that is easily discarded and reshaped as someone else sees fit. She, and everyone else in the universe lost her kids, spouses, parents, siblings, numerous friends and allies, livelihoods, and ultimately lives, being 'reset' to zero, repeatedly for years, due to bordeom and whim. And she went a little insane as a result.
But not bad insane. Even if everyone in her universe worries about her now and she's been committed a few times. She just doesn't want to lose her existance and sense of self, or to see reality reset as if nothing that had happened mattered...again.
LJ name comes from the fact that in every incarnation, at the very beginning Usagi is woken up by her alarm clock and she screams that she is late - usually by her chicken-shaped clock.
