I've done a little work with detachment. You really have no power over anyone who has any type of problem. You cannot fix or change anyone. Is there a way that you can still love her but separate your feelings from her's? That is what detachment is. You can detach from someone but still be in the same room with them. It doesn't mean that you don't love her. You may be a sensitive individual who can sense other's emotions well. That is why if we don't find a way to detach we will get depressed as well. I am also talking to myself here as I am a very sensing person.

I hope this help some.
