Mental harassment by lady boss

I was working as a TEACHING FACULTY in Orissa. I shifted to BANGALORE last year. I was offered to work with a B-School as a COORDINATOR. I am working here since last 10 months. As I was promised with classes & other different angles of growth while getting recruited, but time has changed & my lady boss is not at all listening to my words for my career growth which were promised to me at that time. As I was new to the city, I had no idea about the work culture here. 1. They have kept my Original Master's Certificate. 2. I was entitled to work from MONDAY to FRIDAY. But, as a goodwill gesture, on her request, I started working on Saturday as well. Now, when I ask for my SATURDAY leaves, she is threatening me to sack. 3. She interfares in personal life as well. 4. She expects me to spend time even after the working hour by listening to her family life stories. 5. Continuously she changes her directions for a task, so the deadlines get affected. 6. When somebody shouts at me & I report to her, she tells "you are a mere coordinator, you have to tolerate everything & keep your mouth shut" 7. She asks for personal favours during late nights as well. Kindly guide me what to do. I am highly depressed as I can't afford to lose my future as a faculty...
