<u>Answer</u>: Your mind has coping mechanisms that only work when<em> you are in stress </em>
<u>Explanation</u>:
The process of using conscious effort and energy in order to solve personal or interpersonal problems is called <em>coping</em>.
The mechanisms that are used to tolerate or minimise stress in our day to day to life are known as <em>coping mechanisms.</em>
The main goal of all the coping mechanisms is to reduce or deal with <em>stress</em>.
These mechanisms come into action whenever a stressor is present or even before it, incase of proactive persons.

To overcome the stress faced in the presence of stressors our mind has <em>coping mechanisms which come into action and reduce the stress. </em>
