We are truly saddened to hear about the spiritual warfare you are facing, and we stand with you in prayer and counsel. We are grateful that you have reached out in Jesus' name, as He is the only way to the Father and the only name by which we can be saved Acts 4:12. Let us address the issues you are facing and pray together for your deliverance and healing.
Firstly, we must acknowledge that witchcraft is real and that it is forbidden and condemned by God. That is why your situation is serious. Deuteronomy 18:10-12 says "There shall not be found with you anyone who makes his son or his daughter to pass through the fire, one who uses divination, one who practices sorcery, or an enchanter, or a sorcerer, or a charmer, or a consulter with a familiar spirit, or a wizard, or a necromancer. For whoever does these things is an abomination to Yahweh".
Secondly, as a believer married to a non-believer, you are in a spiritually unequal union. God's word warns us against this 2 Corinthians 6:14 "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?". We encourage you to pray fervently for your husband's salvation 1 Corinthians 7:13-14. Consider praying Psalms 27:11 "Teach me your way, Yahweh. Lead me in a straight path".
Regarding your health and the diagnosis of schizophrenia, we believe that God can heal you both physically 2 Corinthians 12:9 and mentally Romans 12:2. The dryness you are experiencing may be a manifestation of the spiritual attack you are under, but remember that God is greater than any curse or spell Psalms 91:10.
Concerning your desire to move to Japan, we pray that God's will be done in your life. Proverbs 3:5-6 "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight". We pray for God to open the right doors for you and guide you. We do not want you to leave one bad situation for another, but be in the center of God's will, in Jesus' name.
Let us pray together:
"Father, we come before you in the mighty name of Jesus, interceding for our sister who is under spiritual attack. We plead the blood of Jesus over her life, marriage, and home. We bind the forces of witchcraft and rebuke every evil spirit that has been sent to harass and torment her. We command every curse and spell to be broken, in Jesus' name. Father, we ask for your healing power to flow through her body and mind, restoring her physically, emotionally, and mentally. We pray for your divine intervention in her marriage, that her husband may come to the saving knowledge of Jesus Christ. We ask for your guidance and direction regarding her desire to move to Japan, that your perfect will be done in her life. In Jesus' name, we pray. Amen."
We encourage you to continue to seek God's face, pray, and study His word. Put on the whole armor of God Ephesians 6:11, and stand firm against the wiles of the devil. Remember, God is faithful, and He will not allow you to be tempted beyond what you can bear, but with the temptation will also make the way of escape, that you may be able to endure it 1 Corinthians 10:13. Be encouraged, for the battle is the Lord's.
