17 Times Grey's Anatomy Made You the Person You Are Today

And we learned that we can mourn so many things at once. Thanks, Grey's Anatomy, for testing the limits of our sadness.

During this plane crash, we finally hear Mark say "I love you" to Lexie, but it's moments before she dies, so we got robbed a little. Also, Arizona loses a leg, Derek's surgical future is jeopardized, and Cristina and Meredith suffer PTSD for months after. There are so many simultaneous tragedies that Grey's really taught us a lesson about emotional multitasking.
