You might be dealing with stress, maybe too much strain or not enough rest. The human body reacts to stress in such a way that all these things can happen.

Symptoms such as fever, headache, throwing up, diarrhea, and nervousness could point towards a stomach bug or food poisoning. These might also leave you feeling light-headed or generally unwell.

If your condition doesn’t improve or gets worse than before, please see a doctor so they can examine you properly and give appropriate treatment options.
