Burnout is what happens when you’ve been stressed out for a long time and you’ve reached the point of being totally exhausted – physically and mentally. The Texas Medical Association has fit it into three stages: stress arousal, energy conservation, and exhaustion.

Stress arousal: You might notice that you’re feeling pretty irritable, or picking up nervous habits.

Energy conservation: At this level, your body is trying to avoid using energy. You might feel tired, procrastinate a lot, or not care about anything.

Exhaustion: You might feel sad all the time or depressed, have stomach problems, get headaches, or just avoid everything.
