An addiction could be your heart screaming, "Pay attention to me! I am hurt and wounded." Yet you refuse to deal with the memories and emotions from the past because they seem too painful to handle. Good news! You don't have to handle your emotions....just hand them over to our loving Father.
What memories have you buried? Take a second to ask God to remind you of pain you have hidden away from God and yourself. As He brings them to your mind, ask Him to take them for you. Ask Him to heal you of that pain. If necessary, ask God to forgive you or someone else.
This is a process. It may take several times, or the help of a family member, or even the services of a Christian counselor. The important thing is that you trust God with your pain and stop trying to bear the burden of it in your heart. Your heart cannot handle it and was never meant to carry that weight. That could be the reason your physical body constantly desires the soothing of something other than God...something that has now become an addiction.
When Peter saw Jesus walking on the water in Matt. 14:28 Peter said, "Tell me to come to you on the water." Jesus said, "Come." And Peter went. Now it's your turn. Make things right with your heart and the rest of your physical body will eventually realize it has been SET FREE.
