Physical and Emotional Fatigue
Physically, you feel worn out. You don’t have energy for things that used to be easy to do. You probably have trouble falling asleep, waking up often during the night or sleeping too much.
You could also start experiencing feelings associated with depression include hopelessness, guilt, irritability, or other (more serious) symptoms. You might suddenly find that you now have a shorter temper. Perhaps you’re feeling more irritable; prone to angry outbursts, both at work and at home.
