Well, knowing now that she does have a lot of issues that could very well be caused by ADHD or something else, wouldn't be able to say without knowing more details... It still doesn't change the fact that she just doesn't want help. The part about "I don't need your help" and the contradicting "you're my life saver!" sounds a little like borderline personality disorder, because in BPD, views of people can change drastically one day to the next. One day you're her best friend, the next you are her enemy, for example. But I can't do more than just speculate because I am not a professional and don't know her. If she doesn't need YOUR help, would she be willing to see a professional for help?
