She'll find herself but she has to do it on her own. You cannot help her with this as much as you would like to. She feels guilty, she hates herself for not feeling the way she should be feeling and she wants comfort and somebody to be there for her. It's not your responsibilty, she isn't your priority, and your love for her is working against you right now. And you are actually stunting her growth as well because you are cushioning the blow she is receiving from reality and lonliness and having to possibly make changes and become a better person.
It's going to take a little bit of tough love but you have to let her know that this is what she wanted. This isn't helping you either, it's keeping you pining for something that isn't going to work. She doesn't feel that way no matter how much you comfort her. You have to accept this reality and keep her from trying to drag you down too. You are going to look back at this in some good time and ask yourself "What was I doing?" I promise you.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
