If i woke up at 5 in the morning for 2 days did really hard work all day and slept for ten hours the third night was up for only six hours could i still feel tired from all the work i did over the weekend or where is my tiredness from an illness?

Fatigue from exertion has many components - quality of sleep around the incident, adequate food intake and hydration, and most important, the overall fitness of the individual. Someone used to vigorous exertion would be less tired; someone for whom exercise is not a regular habit, could be excessive fatigued and tired. Good work working hard on the weekend!
