I will make a full chapter regarding surrender, idols and nervous system, thanks for the question!!! I spent some time reflecting on your answer with God and was taken back to times I have felt the same way. I will focus on the surrender and nervous system first, because they do go hand in hand. The more we can surrender, the deeper we can rest in Him and his presence. That is where His fruits; love, joy, peace, goodness, kindness, patience, forgiveness, self-control, fear of The Lord, nervous system being healed and so much more. How to even surrender? It is about alignment, agreeing to fully surrender to Jesus in your heart, mind and soul. Repentance is a continous journey, as we continously will make mistakes, but grace and mercy covers us when He sees we long to be with Him and not the world. It is important to truly seek repentance and often we are not even aware we might live in misalignment with God's will and have open doors for darkness, through sin. What has helped me alot to surrender is a simple journey of doing what Jesus was doing to surrender. He fasted for 40 days right after recieving The Holy Spirit. 1# key to surrender and regulating the nervous system is fasting. It strengthens your spiritual discipline, relationship with God, it heals your nervous system at a cellular level if we can remain in a fasted state for above 36 hours, without sugars and any food, only water. Our body literally starts to heal at a cellular level, removing toxins, disease and unwanted things that affects our body. This is something we should have as a part of our spiritual life with Jesus. But a fast alone is not what God seeks of us, a fast is about seeking God through surrender and sacrifice. All major biblical breakthrough events include fasting, so if you are looking for a breakthrough, fasting is my number one advice. As you get tempted again and again to eat, you will instead fold your hands and pray to focus on God and come out of agreement in your heart and mind of the temptation. This strengthens your relationship, resillience to temptation and keeps you fully surrendered.
