First, remember that GOD LOVEs YOU!! No matter what you have done. Each time you feel the urge to give into temptation replace it with the TRUTH-GOD's Word in the BIBLE!! He promises to never leave you or foresake you. Jesus has already died for the sins you have committed and everyone else and for all the sins that are to come. Trust in him, You say you do not have the strength but lean on Christ and he will give you strength he can pick you up carry you and take you through. Like Pslams 23 says, "Ya thou I walk through" Key Word "Through" he doesn't say you are going to stay there he says through he wants to go through with you turn to him when you have the desire to turn to the addictions-they are parasites that the devil is trying to devour your heart and soul with and God is the Medicine to rid you of the parasites.
Find a good Bible based Church, support group that is Christ centered and Christian counselor walk away from any friends or things that are of the world or that you may have participated with in the addictive things that have you in bondage and pray pray pray for GOD to help rid you from the bondage of addictions. Surround yourself with Christ centered places, people, workplace, and friends.
May God be a shield around you and open your heart to be receptive to his love and mercy and free you from the bondage of satan's strong hold and
give you strength to rise up through GOD so that you may be a living witness and testimony to his grace, mercy, and undying love. I ask this in Jesus'
Holy name. AMEN!! and May God continue to Bless and Keep You!!!
