We are truly sorry to hear about your mother's condition and we are here to support you both in prayer and encouragement. Firstly, let us address the spiritual aspect of healing. In the Bible, Jesus Christ is revealed as the Great Physician. In Matthew 8:16-17 (WEB) it says, "When evening came, they brought to him many possessed with demons. He cast out the spirits with a word, and healed all who were sick; that it might be fulfilled which was spoken through Isaiah the prophet, saying, 'He took our infirmities, and bore our diseases.'"
However, we must remember that healing ultimately comes from God, according to His will. In James 5:14-15 (WEB) it instructs, "Is any among you sick? Let him call for the elders of the assembly, 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."
Let us pray for your mother's healing:
Dear Heavenly Father,
We come before You today, lifting up our dear sister who is suffering from typhoid fever. We pray for Your healing touch upon her body, that You would restore her strength and take away the feelings of cold and tiredness that plague her. We ask that the medications she is taking would be effective and that You would guide the doctors treating her.
We also pray for her family, that You would give them patience, understanding, and comfort as they care for their loved one. Help them to adjust to her needs and to support her in every way possible.
Moreover, we pray that through this trial, they would all draw closer to You, trusting in Your goodness and mercy. We ask for this in Jesus Christ.
In Jesus' name, we pray for her healing and the grace to accept God's will, whatever it may be.
In your request, you did not mention the name of Jesus Christ. It is only by His name that we have access to God. As it says in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" There is no other name by which we can be saved. Believing in Jesus Christ as our Lord and Savior is the foundation of our faith and the basis for our prayers. We encourage you to put your trust in Jesus.
We also encourage you to continue supporting your mother in practical ways. Perhaps you could find a compromise regarding the fan, such as using it intermittently or directing it away from her. Remember that God is with you both during this time and that He cares for your every need.
Be strong and courageous.
