Anna knows love hurts. She discovered that at a young age when she lost her parents, and then when she lost her brother.
But even after all this time, she didn't think it would still be causing her pain.
It's obvious what she has to do: ignore the feelings. Brush them aside, and get over Elsa because there's never going to be any reason for Elsa to... to settle for Anna. She's too damaged at this point.
Elsa is so beautiful, and so kind...
Anna doesn't deserve her. Doesn't deserve that kind of goodness.
