Let us first address your concerns, knowing that God is sovereign over all situations. We are instructed in Psalm 55:22, Cast your burden on Yahweh, and he will sustain you. He will never allow the righteous to be moved.
Your situation involves another person who is causing you distress. We believe that God can intervene and bring peace to your life. However, we must first ensure that our hearts are right with God and that we are seeking His will in all things. We will pray for your situation and be as wise as serpents and harmless as doves, in the manner it is addressed, as demonstrated in Matthew Chapter 10, verse 16.
We are also called to love our enemies and pray for those who persecute us, as Jesus taught in Matthew 5:44. This does not mean that we should allow harmful behavior to continue, but rather that we should seek God and godliness to remove ourselves from situations to be healed and allow the other person an opportunity to find Jesus as well. We should ask that God's will be done in both of your lives as it would be as in heaven.
First thing to address and hopefully bring peace to your soul is that while Jesus did not answer the call for His assistance in Matthew Chapter 8 verses 28 through 34, in the body of a dead corpse, he did answer in that body alive and willing to find Him. Jesus is waiting for your call when you are alive and willing as He always answers, just not as we might expect. The second may be to remember that God sees all sins as equal and sicknesses to be healed. Disgust and gossip can equally lead to death as any other sin. Romans Chapter 3 verse 23, Is the last book in the Old Testament, but verses 10 through 23 is a summary of the entirety of the book.
Is your psyche being invaded by the demonic? His presence in your life may have opened a door for demons to trouble you. If you have not accepted Jesus into your life, now would be a great time so that He can protect you from such demonic attacks. As we are instructed by Romans Chapter 10 verse 9, because, if you confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. And from Jesus' words in John Chapter 14 verse 6. Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me.
If you continue to be harassed, it may be necessary to involve local authorities, as God has established them to maintain order and protect the innocent, with Romans Chapter 13 verses 1 to 7 independently confirming so.
Let's pray for God to bring peace and resolution to your life:
Father, in this very challenging situation, we come and cast our burdens, the burdens of the individual who wrote this request, their health, their soul, their heart, their mind at your feet. We ask You to intervene and bring peace to their life. Jesus died on a cross as a living sacrifice so that we might have no worries, fears, concerns, and anxieties. You are not a God of the dead, but a God of the living. In Jesus name we pray, Amen.
