The important thing is to get your job done, and

don't feel bad to answer "no" when she asks weather you finished so and so.
Ignore all no-work related stuff, if you get a cold face, you don't have to give a smiling one back. If she's nagging about work, just answer her in a professional manner every time.
In 9 months or less, you will be free, and meanwhile, you are making a decent salary.
