Swarming Thoughts

I've been studying here at Mainstacks since early evening and am still currently here as I write. Throughout my studying time though, I find my mind to have the tendency to inadvertently wander around and be intruded upon with many many thoughts that are NOT related to human anatomy (which is what my lab exam this week is on)... These thoughts are very distracting and cause me to be unable to focus and absorb the material I desperately need to learn. And it's not that I want to or intentionally think about certain things, but often times different things just trigger thoughts or memories of the past that just clutter my brain and cause me to be unable to focus and be productive, not to mention hinder me from "moving on". The Bible verse that came to my mind immediately was one that Sally gave me recently from 2 Corinthians 10:5, which reads:

"We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ."

I kept on repeating the last part to myself, asking God to please TAKE CAPTIVE MY EVERY THOUGHT and MAKE IT OBEDIENT TO YOU. This is the verse that I use these days in my defense whenever swarming thoughts preoccupy my mind.
