We rejoice with you as you seek God's blessing and guidance in your life. Let us pray and consider God's will for you. It is wonderful that you are looking for a God fearing Christian man for marriage.
Firstly, let's address your work and finances. We must remember the Apostle Paul's words in Philippians 4:11-13 (WEB), "Not that I speak in respect to lack, for I have learned in whatever state I am, to be content in it. I know how to be humbled, and I know also how to abound. In everything and in all things I have learned the secret both to be filled and to be hungry, both to abound and to be in need. I can do all things through Christ who strengthens me."
While it's natural to desire success and increases in patients at work, we should also desire God's will and contentment in our current circumstances. We pray that God will give you the strength and wisdom to serve Him through your work. If it is His will, may He bring more patients to you and help you meet your goals. But we must be mindful in Philippians 2:3 (WEB) it says, "Do nothing from selfishness or empty conceit, but in humility consider others better than yourselves."
Regarding your housing situation, we are thankful that you have found an affordable and pleasant apartment. Remember that God is your provider. He knows your needs and He will supply them according to His riches in glory.
As for your desire to meet a good Christian man for courtship leading to marriage, we pray that God will guide your steps. Be mindful to seek a man who is a fellow Believer. Remember 2 Corinthians 6:14 (WEB), "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?" Psalm 37:23 (WEB), "A man's goings are established by Yahweh. He delights in his way." We pray that God will bring a godly man into your life for His glory and your mutual blessing. And remember Proverbs 3:5-6 (WEB) says, "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."
Concerning your coworker, we pray for God's protection and wisdom. Remember Romans 12:18 (WEB), "If it is possible, as much as it is up to you, be at peace with all men." And also Romans 12:17 (WEB) "Return no one evil for evil. Respect what is honorable in the sight of all men."
In your desire to serve God and write books, we encourage you to seek His will and guidance. If it is His will, may He open doors for you to write books that serve Him and bring income for your needs. Remember Proverbs 16:3 (WEB), "Commit your deeds to Yahweh, And your plans shall succeed."
Finally, we praise God that you acknowledged the authority of Jesus Christ in prayer. It is only through His name that we have access to the Father. As it says in John 14:13 (WEB), "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son." Remember that it is only through faith in Jesus Christ that we are saved.
We pray all these things for you in Jesus' name. Amen.
