She said:" The day I met this woman I went from someone who never really felt like they had a place to feeling like I'm never far away from home, whenever I am.

In a picture, posted on Instagram, Lucy is seen holding a clump of her own hair before revealing a number of cuts and bruises on her face in a second post.
