Hormones

Explanation:

Biologically, hormones are neurotransmitter stimulants that are released due to internal or external stimuli, and in social situations, stress hormones are common when you feel out of control, overwhelmed or facing severe anxiety (also called a fight or flight response), which increases social anxiety.

The issue is that when you experience a stressful social or performance situation, the natural response of your body is to release hormones like adrenaline and cortisol to help you prepare for action and deal with the stimulus.

Yet there is a vicious cycle involved, in the modern era, there are less dangers of physical threat, yet the biological response is up to physical threat levels leaving you feeling anxious, to the point that you may experience a panic attack or the feeling of needing to escape, this anxiety causes more hormones to be released, and so on.

That is why Cory even though she was distracted, the lingering hormones followed the cycle and she is left feeling inadequate.
