I want to thank you for the help that you have given me duri

I want to thank you for the help that you have given me during my stay in your home,这句话对吗?I want to thank you for the help that you have given me during my stay in your home.这是答案写的.可是我觉得后面的my不对.怎么是我的呆在你的家里,我觉得应该用"I".I want to thank you for the help that you have given me during I stay in your home.这样.第一句对还是第二句对?谢谢!
