We understand your concerns
I went through your description. You were stressed out before the tiredness
creeped in and that might explain every symptom. Therefore don't worry.
Stress happens when body and mind works beyond its tolerance level. In the course, the body utilises some of the stored nutrients. But vitamins
are not stored and therefore the only source is eatables. Tiredness feeling, pain, feeling helpless, suspecting that there is something wrong with the body, watching the body and getting distressed are common symptoms of a stressed out person.
Have a nutritious diet for a week or so. Drink enough water. Take proper rest. Sleep for 8 hours. In a week you should be perfect.
Hope this clears your doubt. Available for further clarifications.
