First things first, you need to be filled with the Holy Spirit. Have you said the sinners prayer? When in prayer ask him to fill you with his spirit. Without his spirit you cannot overcome. Come to God in humility. Ask to be cleansed from all sin by his blood. Say in your prayer I give you my burdens, my struggles, my cares. Ask the Holy Spirit to help you in Jesus name. Also you need the baptism of the Holy Spirit and fire. This is power that he gives you. And be prepared for War within yourself. You will have to battle against yourself. To become the person you want to be.
