I feel you bud. I hit a wall yesterday too about being overwhelmed by school and still having to go to work that night. I realized I didn't get enough sleep the night before, so maybe that could help you. When you take time to care for your body, your mind becomes clearer.
Matthew 11:27-29 (the "Scarlet Man"'s words)
All things have been handed over to me by my Father, and no one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal him.
Come to me, all who labor and are heavy laden, and I will give you rest.
Take my yoke upon you, and learn from me, for I am gentle and lowly in heart, and you will find rest for your souls.
