Help on Overcoming Sin/Advice

I am constantly struggling with sin and I have realized that maybe I keep sinning because I don't feel bad about it. So what should a Christian do when he is sinning and doesn't feel bad about it? Any tips/advice would be helpful. I also need help with reading the bible like in consistency. I am not consistent enough with it and I don't read it every day. Some days ago I completed a fast and tried to read 1 bible chapter a day but I didn't finish the whole chapter that day and felt discouraged. So should I do the one year bible reading plan that comes with my kjv or do you think there is a quicker plan that isn't too overwhelming like reading an entire chapter in a day. I feel like I am far from God and I think it is because I keep sinning and I have tried several things to quit it but I always end up coming back to the sin. Give me any suggestions and pray for me if you can, thank you.
