I’m sorry to hear about your struggles with your family. First, I think you should read this on Spiritual Warfare. It’s possible that you, and your family, may have stepped into an area where you should not have been.
I will pray for you that God will give you eyes to see what He is doing in your life at this very hour and also that you will submit to the process that he is taking you. May His grace to endure be upon you, in Jesus Name, Amen
