My question involves landlord-tenant law in the State of: Texas

So a few days ago I went to tell my landlord (well, actually the property manager who happens to be the daughter of the landlord since we're in college) that I wanted to renew my lease for the upcoming year. She said that she was sorry, but she had already promised the place to new people as she wasn't aware that I would be staying another year (I had told her that when I moved in). I have paid all my rent early or on time and I've kept the place spotless. Nothing has been broken.

Is there anything I can do? This house is perfect for me to live in because of the location and condition of the house. I do not want to give it up. With five months the other people would have more than enough time to find a new place to live. Are there any laws against this or anything particular I can do? I'm kind of desperate. I've had to move three times within the past two and a half years due to room mates changing and I have a ton of stuff.

Any help would be greatly appreciated, thanks.
