Anxiety is as much about uncomfortable physical sensations in the body (viscera) as it is about repetitive uncomfortable thoughts in the mind.
Find powerful mind-body tools and practice them diligently.
I recommend you look into Havening, a technique that involves soothing touch and mental stimulation. It's been researched as an effective anxiety treatment.
Diet and exercise also play a role. Complex problems require multifaceted solutions. Your life right now might have to be about working through the anxiety. You have to study, experiment, and evaluate different techniques as solutions for you.
What you learn along the way will make you a natural leader.
