Verbal agreement after written lease agreement problems

I am trying to figure out if my landlord has any way to make us stay in our house we are renting. We are currently living in Indiana. We signed a lease (written lease) starting September 1, 2009 to October 1, 2010. On May 13, 2010 I called my landlord and told her we were planning on staying put right now, we were expecting our daughter and I wasn’t about to be moving when she was 3 months old. She said ok she’ll write down the date that we talked (and told me to do the same) and it would be considered a verbal agreement.

 On Tuesday, December 14, 2010, I called our landlord to tell her that our situation has changed and that we are not going to be able to afford the house we are currently renting, we were planning on moving out by March 1 (I didn’t get the chance to tell her that date), for much longer than a couple more months. She got upset and said that we had a lease and we cannot just move out and blah blah blah. I explained to her that we were going to move in with my parents to try to get back on our feet, and her response was "If your parents are going to let you live with them then they’ll probably pay your rent so you can stay here." I was like you have to be kidding me.

 But my question is, since its a verbal agreement that we were going to stay past our October 2010 lease is there anything I can do to get out of it? Is there any legal standing that they have? And if there is anything I can do where can I find some documentation. I have been looking online all day and I keep finding things, but I don’t think they are from reputable sources.
