Chills, fatigue, fever, nausea, headache. Gastro is going around could it be this despite no vomit or diarrhea? Tolerating food in small doses.

Gastroenteritis. It is possible that this is what you have, although it may just as easily be something different than what is "going around". As long as you are getting better, not becoming severely dehydrated, able to hold things down, you should resolve uneventfully. If, however, you become worse or cannot take in liquids and food would definitely go and see your family doctor.
