Wow... you have alot going on and it's so wonderful that your prayers are very specific for your son. I experienced something similar and was connected to a ministry that was after their own flesh instead of following God's word. Today I am walking in deliverance from all the strongholds I picked up along the way. I am also thankful for that experience because it has helped me to trust God more, to have greater faith in hopeless situations and to look to God. The enemy, the devil is already deveated. He will try to distract us but he has already lost the fight. Your son will come out of this stronger than ever before and will have a great spirit of decerment when God is ready to deliver him from this mess. I pray that the Holy Spirit huffers over your son while he is in this dark place. But he will see the light and will walk in it when he starts his own ministry and will recognize any scemes of the enemy because of this experience. Just keep the faith and stay strong for God will give you all He has promised you.
