Please please help me! I think the spiritual is starting killing me physically?

I have no idea what that guy was doing and you listen to that inner voice telling you that something isn't right about him. I am very sorry about what you went through and every behavior that you have noted including this "cult" camp to this guy performing witchcraft is not following the teachings of Christ. If you read 1 John 4:1-6, this scripture clearly explains about being aware of false prophets. Continue to test the spirits to see if they are from God if not then stay away!!! Since we know that there are lots of false prophets and people who lead others astray, the bible calls us to guard our hearts and stand firm in the truth. Go to God in prayer and Him for your guidance in this area and pray about going to a spirit-filled church. I will be praying for you as well.
