I have a cold. I'm coughing and I have a sore throat. Could that be the reason why I'm really tired? Also my period is 3 days away.
Fatigue. Yes. Any viral illness has the potential to make you feel tired, along with dozens of other possibilities, not the least of which is depression. This is the time of year that people are getting sick of winter (although perhaps not in houston) and having seasonal depression. If this does not clear up when your cold ends, see a doctor. Best.
