After a comment like "eat a banana" I feel stupid to write "eat the Holy Communion"... but I am doing it anyway, assuming that your question and your struggle are serious (just as the struggle of any Christian who wants to take himself seriously and is honest with himself).
If salvation depended solely on our willpower and our ability to abstain from sinning than the Law of Moses would have been enough and the sacrifice of Jesus Christ would be ... just a narrative that must fit a larger picture. Of course, this is not the case.
In reality, the Holy body and the precious blood of Jesus Christ are the center of the Christian life: the Holy Eucharist is the concrete means by which you unite with Christ and are given power (from outside of this world) to deny this world with its temptations.
What do I do in order to renounce this world and have power to continue in the journey towards the kingdom of God? I go to the church (the eastern orthodox church), I pray, I read the Bible, I try to fast and I eat the Holy Communion. The same things that christians have been doing for centuries.
No breaking news, no shortcut, no other way.
