Mind and body connections

How do decipher if a physical and/or emotional pain is coming from my body versus my brain? Is it important to determine where it’s coming from? I’ve know Brooke teaches all emotions start in our brain. But I’ve also read literature about mind-body-spirit connection. In Scholars so far, (I am only two-months in), I’ve listened to teachings about our brains. As I have an over-active brain, this has been so helpful for me! But as I experience emotional pain physically, I am unclear if my body is sending signals to me or if my brain is creating it and I need to choose new thoughts.

Thanks so much! I am loving Scholars!!
