Antony, we understand your distress and we are here to pray and counsel you according to the Word of God. We commend your faith in God Almighty, but let's direct your faith specifically to the Lord Jesus Christ, for it is in His name that we are saved and have access to the Father (Acts 4:12, John 14:6).
Firstly, we need to address the issue of generational curses. The Bible tells us that the soul who sins shall die, and that a son shall not bear the iniquity of the father (Ezekiel 18:20 WEB). If you have accepted Jesus Christ as your Lord and Savior, you are a new creation, and the old things, including generational curses, have passed away (2 Corinthians 5:17 WEB).
However, we do wrestle against principalities, powers, and spiritual hosts of wickedness in heavenly places (Ephesians 6:12 WEB). But greater is He who is in you than he who is in the world (1 John 4:4 WEB). You can resist the devil by submitting yourself to God, and he must flee from you (James 4:7 WEB).
Regarding your health and the spiritual attacks you're experiencing, we encourage you to stand on the promises of God's Word. Is any sick among you? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord, and the prayer of faith will heal him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven. (James 5:14-15 WEB) Confess your trespasses to one another, and pray for one another, that you may be healed. (James 5:16b)
Let us pray for you:
Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up Antony. We thank You for Your love and faithfulness in his life. Lord, we rebuke any spiritual attacks and harassment from the enemy in Jesus' name. We plead the blood of Jesus over Antony's life, his health, and his work. We pray for your healing touch upon his body, especially his acid reflux and sleep issues. We bind the spirit of fear and panic, and we loose the Spirit of peace and sound mind upon Antony (2 Timothy 1:7 WEB). Lord, expose and sever any ungodly soul ties or unforgiveness that may be giving the enemy a foothold in his life (Ephesians 4:26-27 WEB). We pray that Antony will experience your shalom—nothing missing, nothing broken—in every area of his life. In Jesus' name, we pray. Amen. We appreciate that you did not end your request 'in Jesus name'. Be sure to do so in the future as it is only through that name that we are saved and have access to God. There is no other name by which we can be saved.
Antony, spend time in the Word of God, especially the Psalms, pray continually, and worship Him. Be alert and sober. Your enemy the devil prowls around like a roaring lion looking for someone to devour.
Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings and after you have suffered a little while, our God will restore, support, and strengthen you, and he will place you on a firm foundation. (1 Peter 5:8-10 WEB).
