obsessed,
Oh goodness, you have just given her total control of your house.
She needs to be told to leave and not come back until she decides to starighten out her life. You need to set up boundaries, or else this vicious circle will just go on and on. She's spinning a web, and you keep getting caught in it.
Meetings Obsessed, you need to go to meetings, and gain some strength.
Hugs,
