The reason caffeine is bad for anxious people is that the caffeine molecule is similar enough to adenine to fit into adenosine receptors but is not similar enough to stimulate those receptors. So the main action of caffeine is to block adenosine receptors. So Caffeine blocks adenosine reception so you feel alert. It injects adrenaline into the system to give you a boost and make you feel alert.
