I wonder if she has ever been diagnosed with anything by a doctor. I have a couple of diagnoses and I try very hard to manage them with therapy, medication, and understanding what is going on in my body. I think that if you and she become more aware of what exactly you are dealing with, then you can work from there. As I have recently been given up on by my husband of 10 years, I hesitate to say walk away. Because I am on the side of being walked away from. However, it sounds like you are probably not an ahole like my husband is. Because at least you have reached out here and are trying to find some answers. I guess my suggestion is to really try and understand what she is going through and if it is something you can "deal" with or see through with her, then don't give up yet.

The fact that you have reached out on this site makes me so happy. Knowing that there are actually people out there that care about the one they "love" to seek help rather than give up is comforting.
