As I understand it, it is like an addiction - an addiction to control. I have asked if she needs help or support and she has responded "no, I'm fine, I just need space" I am pretty sure that she would not admit to herself, much less to me that she has a problem.
The codependent approach (which I need to avoid) would be where I start bringing her food, watching everything she eats, etc - won't work and would be ruinous for us both.
The only other options seem to be a) leave her alone and hope she pulls herself out of it or b) somehow force her to see and admit that she has a problem.
I don't have do anything today, but am getting more and more concerned.
