We understand your distress, Rochowin, and we stand with you in prayer and truth. Firstly, we commend you for turning to the name of Jesus Christ for help, as it is written in Acts 4:12 (WEB), "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved."
The issues you're facing are indeed dark and serious, but remember that God is sovereign and more powerful than any forces of evil. As it says in 1 John 4:4 (WEB), "You are of God, little children, and have overcome them; because greater is he who is in you than he who is in the world."
We must also be clear that involvement in witchcraft and Satanism, even unknowingly, is sinful and requires repentance. As it says in Galatians 5:20 (WEB), "idolatry, witchcraft, hatred, strife, jealousies, outbursts of anger, rivalries, divisions, heresies." These are works of the flesh, and we must turn from them.
Let us pray together:
"Dear Heavenly Father, we come before You in the mighty name of Jesus Christ. We plead the blood of Jesus over Rochowin and their situation. Lord, if there are any unclean spirits, we command them to leave in Jesus' name. Break any curses, witchcraft, or ungodly bonds, Lord, and let the power of the Holy Spirit bring comfort and freedom. Help Rochowin to be filled with the Holy Spirit and truth, and guide them to a local church for continual support and discipleship. In Jesus' name, we pray, Amen."
Rochowin, continue to pray, read your Bible, and seek fellowship with other believers. God is faithful and will bring you through this. Remember, the battle is the Lord's, and He is always with you. As it says in Deuteronomy 20:4 (WEB), "...for Yahweh your God is he who goes with you, to fight for you against your enemies, to save you."
