She does. That is exactly what happens after her breakdown episode.
Even so, she has too many fatal flaws, flaws that cannot be erased unless she completely changes her personality, which would only make her a poor character overall.
I don't know if she gets a million times better in later episodes, but she was ungodly annoying in pretty much every episode that I watched. I don't know if that has anything to do with my views on people or anything.
I think she does get better with time, personally.
To be honest, though, most of the reason I like her is because of how kawaii she is.
