I think the hands and the facial expression in the mirror represent feelings of fear and strangling/suffocation -- perhaps not enough space in a relationship, or prohibiting factors preventing her from acting in how she needs to. That is who she sees - how she feels about herself and what she is going through. While the girl is pretty, I don't think this is about looks.
On the "real" side or non-mirror side, she is not being held or choked. The reality is, nothing stops her from doing anything (except the terrors of her own mind). I get a sense that she could pack up and go tomorrow if she wanted, but she won't.0
