Flu like symptoms

So yesterday I all at once got super sick. All of the flu like symptoms except for puking and diarrhea (however, about two weeks ago I had the stomach bug). I’ve tried different nose sprays and cold/flu medications along with ibuprofen but NOTHING is helping. My nose is so clogged with thick but watery yellow snot, my eyes are watering, I’m lightheaded, have a pounding headache, etc. Also, this has never happened before, but I haven’t ate anything since yesterday around lunch time and I keep burping and passing gas A LOT.

I’m not too concerned over this just thought it was all weird and wanted others thoughts! Thanks!
