Thank you for sharing your heart and these burdens so honestly. The weight of these things together, a costly car repair for your daughter, financial pressure, health struggles, work needs, and hopes for the future, is real, and God sees it all. Nothing about your situation is hidden from Him. He sees what others cannot see, and He looks on you with compassion and sympathetic understanding of your weaknesses and needs.
I am praying with you that the test on your daughter's car would show a simple cause, like condensation, rather than a failed head gasket, and that the Lord would provide a repair that is not beyond what you can bear. Only God can truly provide healing and help beyond our own ability, and He is able to work graciously on our behalf when we bring these practical needs to Him. At the same time, we can trust His care even if the answer is more costly than we hope, asking Him to make a way for provision.
I am also praying for your need for work, including this interview you mentioned. God knows your financial strain and your desire to provide. Ask Him to open the right door for a better paying job according to His wisdom, and to give you peace as you wait on His timing.
For your health, I understand how discouraging it can be to carry extra weight while dealing with PCOS. The Lord went about doing good and healing all kinds of sickness, and He still cares about the body. Bring your health to Him and ask for strength to care for your body with wisdom, for guidance for any doctors who help you, and for grace to walk patiently through a difficult condition. He understands the struggle in a way no one else fully can.
You also mentioned longing for a good spouse one day. That desire is God given, and Scripture teaches that marriage is His design where one man and one woman become one flesh, a profound unity where two become one, a lifelong covenant. Jesus also taught that in the resurrection we will not marry as we do now, but will be as the angels in heaven, which reminds us that marriage is for this life and points us to the even greater and eternal relationship we are made for with God Himself. It is good to pray that if it is His will, He would in His time bring a faithful, godly spouse who will walk with you in that biblical design.
Above all these important requests, I want to gently encourage you with what matters most. We often focus our prayers on the symptoms, the car, the finances, the body, while the deepest need every person has is forgiveness of sins and salvation through Jesus Christ alone. It is better to enter heaven with hardship and weakness in this life than to have every earthly problem solved and miss eternal life. If you have not already, put your trust fully in Jesus for the forgiveness of your sins, and keep that at the center of your prayers. From that place of being right with God, you can bring every other burden to Him with confidence.
So I pray that God would show you His compassion, meet your daily needs, grant wisdom for the car and the job, give you strength for your health, and guide your future according to His good will, and above all draw you ever closer to Jesus, in whom we have our greatest hope.
