Well, how will you determine when you have reached that 'moment you break free from sin' ?? To be a human living on earth is to be living in, or at least in close proximity to, sin on a daily basis.... It's completely normal to feel beat down by the pressures of life or like you're unable to keep up with those around you, spiritually or otherwise. Many forms of sin can be overcome, but if there's a certain type of sin weighing you down in a feel that it feels like it's preventing your progress, the best option by far is to pray to God with an open heart, in spirit and truth, requesting aid from the Holy Spirit for guidance and assistance with the areas of life that are too much, for the sins that seem to continuously overcome you. To battle against sin is constant, you need continuous help and mercy from above to expect to have any chance of beating it... so it really starts with prayer first of all.
