Why do I feel tired and irritable?
assistant
You may be feeling tired and irritable because you are not getting enough sleep. Try setting a regular bedtime and sticking to it, even on weekends. Make sure your bedroom is dark and cool and that you keep the temperature comfortable. Exercise regularly during the day and avoid caffeine late in the afternoon. If these steps don't help, talk to your doctor about other causes of fatigue such as anemia or thyroid problems.
