Anna was in a low point of her life where she felt worthless and unable to connect to people. All of a sudden she makes contact with a girl who gives her an immediate and deep connection, and a feeling of worthiness. That's the basic aspect, but it gets deeper when you consider the familial connection they have, and the way their relationship becomes very reciprocal (Marnie turns out to need Anna as much if not more than Anna needs her).
