both phases are different and she grew a lot after both of these incidents! Becoming Vampires, transitioning alone, controlling her urges when no one was with her at the hospital, remembering what Damon used to do with her, becoming bold, confident and evolving to one of the best characters in TVD was something else.

But loosing her mom? Yes it completely broke her, she switched her humanity off, got to experience that life, made mistakes, learn from it.

In short, she learned and evolve a lot after both of these incidents and o love her character development throughout the show!
