If you would like help in this issue check out 'Setting Captives Free.' It is an excellent online ministry that is soundly Biblical with a daily course to battle these sins with the Sword of God and the strength of His Spirit. God is holy, holy, holy!
But what this brother is saying is right. A course might help, but it's about entrusting your life to Christ. God is wiser, smarter, stronger than any man. He knows the best way for us to go, even if its hard at first. Consider the Israelites fleeing Egypt... It was difficult for a while, their disobedience caused setbacks, there was battles, but they eventually made it to the Promised Land. Onward soldiers of the Lord, persevere, we have victory in Christ.
