sister Sakeena, Hussain Mahammed is right, try to show the beauty of islam to your mom, perhaps she did that because she didn't know Islam is a very good faith. I will give you a true story of a man who embraced Islam while his mother against it strongly. This was really happen in my country. After his family knew of his convertion, they didn't accept him anymore in their house, but then he regularly visited his family, no matter how bad their act to him, and he patiently treated, especially, his mother in a very good way, he took care his mother while she was ill of cancer, and there're no brothers and sisters of him who did this more good than him to the mother. And, you know what happened next? two months before the mother passed away, she had accepted islam. It was because of the beautiful act of his son to her. I pray your mom will sonn recognize the beuty of islam and accept it.
salam
