It's beyond my level of expertise to be able to suggest much of anything specific with regard to this. Personally I'm inclined to say that trying to figure out what's going on in your daughter's head (whether this is her mental illness or attention seeking or both) is a losing battle. My thinking would be to get with the mental health professionals, teachers & school counselors (if any) she sees & work out a behavioral plan for how to consistently respond to the behaviors you're being drawn into over-&-over. Right now your daughter has you pretty-much wrapped around her little finger, so to speak, from the sound of it. You're going to have to come up with a plan to extricate yourself. And, at least to my mind, you're probably going to need some professional help as well as cooperation, hopefully, to accomplish it. Best wishes...
