Nausea, dizziness, slight headache and loose stools for the past week.

Seek help: The concerning part of your history is the dizziness. If you are having significant amounts of loose stool/diarrhea and limited oral intake, it's possible that your are dehydrated with low blood pressure. This could all be from a bothersome viral infection but hard to say in this forum. I would encourage you too seek in-person help, as you may need at least some intravenous fluids.
