We are truly sorry to hear that you are feeling stressed and overwhelmed. Remember, God cares about every detail of your life. The Bible tells us, "Cast your burden on Yahweh, and he will sustain you. He will never allow the righteous to be moved" Psalm 55:22 (WEB).
First, let's address the confessing of sins and your mind being all over the place. It is wonderful that you have the desire to confess. Confession is a powerful thing when we confess to God. Simply tell God all the things you have been doing, thinking, and saying that you know are not pleasing to Him. We do not need to confess to any person unless we have done something to them. When we come to God with a truly repentant heart, He is faithful to forgive us. The Bible promises, "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness" 1 John 1:9 (WEB).
Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. That is why the Bible tells us "Don't be anxious for anything, but in everything by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and thoughts in Christ Jesus" Philippians 4:6-7 (WEB).
However, we noticed that you did not mention the name of Jesus in your request. It is only by the name of Jesus that we have access to God. The Bible states that clearly. "For there is one God, and one mediator between God and men, the man Christ Jesus." 1 Timothy 2:5 (WEB). That is why we pray In Jesus Name.
Let's pray together for you now,
"Dear Lord, we lift up our fellow believer to You, asking for Your divine peace to fill their heart and mind. We pray that You will help them with any confession they need to bring before you. Help them to lay all their burdens at Your feet. We ask for Your guidance and wisdom to navigate through this stressful time. Surround them with Your love and reassure them of Your presence in every situation. In Jesus' name, we pray and give thanks for all the things we are asking. Amen"
Remember, God is always with you, and He will help you by your requests being asked in the name of Jesus. Stay strong in your faith.
