Thank you for sharing so openly what is on your heart. I have prayed for you and for your daughter, and I want to encourage you from Scripture.
The anxiety you are feeling is something God understands and cares about. The Bible speaks about the condition of our hearts and asks whether there is rest or whether there is turmoil and unrest within us. God has given a promise of rest to His people, and He invites us to enter into it. That rest does not come from trying harder in our own strength to be calm or to earn His favor. It comes from trusting that Jesus has already done all that is needed for us and resting in His finished work by faith. When anxiety rises, God invites us into a close, loving relationship with Him as our Father, not a distant or formal one. He wants you to bring your worries to Him simply and honestly, to cast all your care upon Him because He cares for you. As you do, He promises a peace that goes beyond understanding to guard your heart and mind in Christ Jesus.
For your driving theory test, it is understandable to feel pressure when there is a lot to learn and the test is still months away. Try not to carry all of those months of worry in one day. God is gracious and patient with us when we are learning and being tested. Even great men and women of faith did not pass every test perfectly the first time, yet God remained gracious and gave them opportunity to grow and try again. Do your part faithfully by studying a little at a time and preparing well, and at the same time place the outcome in the Lord's hands. You can pray each time you study, Lord, I give this time and this future test to you, help me to learn well and to trust you with the result. That daily practice of entrusting the future to Him can replace anxious thoughts about what might happen with quiet confidence in His care for you today.
I also hear your concern as a mother for your daughter. It is painful to watch your child give her heart to someone who has not treated her with faithfulness and respect, especially when he has hurt her repeatedly and she still chooses to go out with him. God created relationships to be built on love, honor, and faithfulness, and marriage is His design as a lifelong covenant between one man and one woman, with purity and commitment belonging within it. A relationship that repeatedly wounds and dishonors does not reflect that design. I will not ask God to bless a pattern that harms her, but I will pray that God will protect her, open her eyes to see her true value in Christ, and give her wisdom and strength to set healthy boundaries. Pray that she will come to know more deeply how much God loves her and wants what is best for her, so that she will not settle for being treated poorly.
For you, pray for wisdom to speak the truth in love. Continue to keep the door open for honest conversation, to listen, to share your concerns calmly without harshness, and to point her gently to what God says about her worth and about relationships that honor Him. Your role to honor and guide your family is a strong and good foundation, and God can use your steady love and prayer to influence her even when she makes choices you disagree with.
Let me pray for you both.
Father, I bring this dear mother before you. You see the anxiety she feels about the test ahead and the burden she carries for her daughter. I ask that you would help her to enter into your rest today, to believe that you love her and that you are caring for every detail of her life. Quiet her anxious thoughts and fill her heart with your peace. Help her to study with a clear mind and to trust you with the future. For her daughter, I ask for your protection and mercy. Give her eyes to see this relationship clearly, give her courage to value herself as you value her, and draw her into a deeper loving relationship with Jesus. Give this mother wisdom, gentleness, and patience as she loves and counsels her daughter. Lead both of them closer to you and to your will. In Jesus name, Amen.
