For around a week i haven't felt great for usually the first hour i am awake. i have had morning diarrhea and just feel generally a little sicker the 1st hour what is a likely cause?v i am 22 years old?

Several possible causes…most likely viral. (one of which could be COVID-19, but not very likely if only in AMs). Other possibilities are food related and stress. If you have no other symptoms, would recommend observation, keeping a food log, and thinking about possible stresses. If not improving over the next week or if more symptoms, please contact your doctor to be seen/further advice.
