We understand your concerns and want to encourage you during this challenging time. Firstly, it's commendable that you're thanking Jesus Christ for the blessings in your life. Remember, it's in His name that we find strength and hope (Acts 4:12 - "There is salvation in no one else, for there is no other name under heaven that is given among men by which we must be saved").
Let's address your feelings of fear and failure. It's important to remember that fear is a natural human emotion, but God encourages us to trust Him even in our fears. As it says in Isaiah 41:10 (WEB), "Don’t be afraid, for I am with you. Don’t be dismayed, for I am your God. I will strengthen you. Yes, I will help you. Yes, I will uphold you with the right hand of my righteousness."
Regarding your academic struggles, it could be that the stress and change in focus due to your military commitment are affecting your studies. It's crucial to maintain a balance and remember that God wants us to do all things with excellence (Colossians 3:23 - "Whatever you do, work at it with all your heart, as working for the Lord, not for human masters").
Let's pray together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up this dear soul who is feeling overwhelmed and fearful. Lord, please grant peace and clarity of mind. Help them to balance their military commitments with their academic pursuits. Guide them to wisdom and restore their confidence in their abilities. In Jesus' name, we pray. Amen."
Lastly, we encourage you to continue leaning on God and seeking His will in all areas of your life. Remember, He has a plan and a purpose for you (Jeremiah 29:11 - "For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future"). Trust in Him, and He will see you through.
