You can’t concentrate.
Fatigue also affects people cognitively. Many find it difficult to concentrate, that they forget things, and are easily distracted. Brain fog is a common symptom associated with fatigue and many report being unable to communicate well, often not being able to find the right words when speaking or forgetting people’s names.
Simple tasks zap your emotional energy.
Completing simple tasks when you have chronic fatigue can seem like climbing a mountain. As well as being physically taxing, fatigue can also be emotionally and mentally taxing. Stressful situations may have you feeling completely overwrought or agitated.
