Adrenaline?

I have the same situation, whenever i am anxious or scared i feel as if i am in a fog, and my body controlled by my emotions not by me. Especially I can feel it when something important is about to happened and i am not really confident, like job interview or important phone call. Its important to look at the situation from observer self and try to make a rational decision. Also important to understand that adrenaline is a chemical your body produces when you have scary thought, so basically you can control it with your thoughts. Whenever you anxious just breath deeply, hold your breath like 4 seconds and think about something relaxing like lying in a hummock on a sunny day, it helps..
