A tired child is a far different animal than what he or she was, sometimes just hours ago. Then the child was cheerful, full of pep, precocious, smart, focused, impervious to criticism, immune to damage. How these many moods and attributes are reflected by any one child or any one person with MS varies according to one's particular personality. But the effect of fatigue on the overall experience of life is profound. When someone is operating while fatigued, even when that someone is an adult, his or her experience changes dramatically.
Moods become low.
Demoralization can set in. Negative thoughts seem more realistic. Requests from others seem more intrusive. Small worries can become major anxieties. Kind suggestions can feel like hostile criticism.
