Sins Chapter 4

I did it again. Again and again. I keep commit a sin. I don't even know why. Almost everyday when i woke up in the morning, i lie to myself. I told myself that i can do it. Even it is hard but i keep trying and trying. People say, don't give up till you success. I know it is hard for me to do it but i try and try and try. But i don't know why until today i still can't do it. And everynight before i sleep, i told to myself to forget everything about today and start a new day tomorrow. Start with helo and end it with goodbye. But why i still can't? I'm lost. Please, help me. Thanks.
