The wind hit her back, and she noticed that she didn't falter, didn't hesitate. She just kept walking. The pain that had been there for months was still there, as it always would be, but like an old wound, it eventually scarred, only noticed by those who knew them before.
He was always there in her heart, and she knew she would never know anyone like that again. Anyone else faded in comparison to The Doctor, the only man she would ever love. She didn't try to pretend that it wasn't true, that one day he would show up in his TARDIS like nothing had ever happened, because everything had happened. And she wouldn't change it for anything. Not even Canary Wharf.
Without Canary Wharf that storm never would've come, and she never would've told him she loved him. She knew in her heart the Doctor had loved her. She remembered it every day when she got up, every time she saw a man looking longingly towards her. It kept her going, kept her strong. And in a way, it helped her move on.
