If you look at the lives of the saints, you will find many sinners among them. Take Saint Peter. He was chosen by Jesus for a very important task, to lead the Church as the first pope. But he was not perfect. On the contrary! However, he knew that he wanted to follow Jesus, in spite of all his flaws. That is how he became a great saint!
The same applies to you: what seems impossible for you, is not impossible to God. If you continue trying to live in friendship with God, following the Commandments, God will help you with his grace!
