For two days now, I've felt really weird. My whole body feels really weak, I've been exhausted, and there was a few times where I thought I was gonna throw up but I never did. I can eat, but I'm not starving. I have no other symptoms (headache, diarrhea, stuffy nose, etc). I've also been very anxious for the past few days so maybe that's it? I haven't been able to sleep and just feel generally awful, I don't want to feel sick like this anymore :( If I haven't thrown up and it's been 2 days and I have no other stomach issues and can eat it can't be a stomach bug right?
