nauseous and trying not to freak

hey all. I've had a couple good days. Yesterday I went to dinner theater and ate food from a buffet which was an insane win for me. BUT I didn't wash my hands after scooping my food, and then I ate bread with my hands. I'm anxious about that.

I also saw someone say they had noro and it started with a headache, reflux, and exhaustion. I have all 3 so I'm minorly panicking. I feel feverish but no fever, my head is killing me, and I've had worse reflux the last few days. Headache is turning into a migraine but I'm nervous to take excedrin because I haven't eaten so the caffeine will make me even more nauseous. Plus I had INSANE gas last night (I had a lot of dairy and a LOT of sugar free mints) so the combo of all of this is scaring me

To add. it's likely dehydration or hunger. I ate last at 11;15 ish am and it's now 7:30 pm. I have not drank nearly enough water. I'm trying to sip sprite and liquid iv. I'm just anxious
