Do not insult the mentally ill by inferring she wasn't in her "right" mind or able to make sound decisions. 
No she is NOT a nut case, she is a sociopath who has no feelings for anyone but herself. She preys on people who are vulnerable and uses her manipulative skills to con them out of their money PLUS she uses the information she fraudulently obtain from them under false pretenses to apply for credit cards with their information. 
This woman will get out and be back to some type of con where she will victimize more people. 
Some many consider this to be a "victimless" crime or a non-violent crime but that is far from reality. 
Reality is that people suffered because of what she did. 
This is often considered a "white collar" crime because the weapons she used to commit her robberies were words and paper work but the end result was the same,she robbed people who placed trust in her.
Bet her story is a tear jerker and she is so sorry for her actions (getting caught).
No cure for her.
