Quoted these because they all lead to a common theme, and that is the extreme self-centeredness of CMJA. This blinds her to the point that she cannot take the advice of others; she has to run the show, even when it is to her disadvantage. She is not able to see this, just as she is not able to understand how she is perceived by others.
If you watched her interview with Detective Flores, you may recall at one point she asked him about legal counsel and whether this was something she should consider. It was very telling when she made a comment to the effect that she wouldn't necessarily listen to a lawyer's advice; I can't remember her exact words, but I was struck by the essence, which was that she would not rely on anyone else but herself.
Her more recent tweets show how much out of control she is right now. As Tuba pointed out, divulging a rejected plea offer via the social media is anything but a wise idea. Her tweets today about letters being sold on Ebay is yet another manipulation; if you search Ebay for Jodi Arias, you will not find any letters offered. Surprise, surprise, CMJA is lying again!
She may be feeling more desperate now and if tweets continue, they may become more bizarre.
I don't know how Nurmi and Wilmott have dealt with her all this time. It makes me cringe to see CMJA and Wilmott whispering to one another, but this may have been a way for JW to try to keep things under control.
