Rollercoaster of emotions

She wanted me last night to adopt her sister, Karizma. Ths morning I found out that she told her mother that we should take Kari here, because we could make room for her, and her mother's house is too dirty and messy and there is no room and she would not be able to take care of her anyway because she is too poor and the house isn't hers anyway so we should have her.
Today, I have to buy her an android phone because her ipod doesn't charge any more and she doesn't want the crappy phone and the android would serve the purpose of both devices and even though I do not have the money to do this because she got herself into the hospital and I've had to spend so much on gas and she didn't like the food I already bought and I had to buy more and that wasn't good enough so I had to get take out and I just do not have enough money to keep replacing things over and over and also have to get her bloody glasses because she was careless with both of the pairs she had, but that's not important because she doesn't care about it.
Good greif, even if I had a million dollars I could not keep up with what she wants, because it would never be enough. 
and she screams and screams, tears things and breaks things and says horrible things to me trying to get me to do whatever she wants right now...
I am so tired.
