I'm so scared and paranoid?

So today I had greenish-yellow diarrhea, I've had food today and it tasted good; I had lots of water, I'm so scared I don't wanna die, I've had a fever though, no vomiting just some stuffy nose. I had flavor ice though, the flavored popsicles, could that be it? Please tell me, I'm so scared. I've been having gas and a stomach ache, I'M SO SCARED.
