I usually have responded to this with "you do not know what I am capable of". I wish these conversations lasted longer at that time - she has tended to stomp off childishly. Hopefully she is in a better place to actually hear me and respond in some way.
She also has deferred things by saying "you have no idea what I've been going through for the last several months". I have responded with "you're right, I don't know, but I'm sure it has been stressful on you too".
I haven't offered any articles or books to her - I thought that would be touting myself as some kind of expert (clearly I'm not) or pushing her to see my point of view or guilt her (I don't want to do this). I also don't know what kind of reading she has done or advice she has received.
