Can you feel covid symptoms the same day you get it?

I feel weird since I got back. My head hurts the way it did when I had covid in the past. I'm going to be so fucking pissed if I do. Not only did they fuck me by not helping me or seeing me but caused me to stay in a room that had no masks but me and were coughing everywhere and anytime I got up to use the bathroom someone took my seat. So I had to sit in a new spot that people were coughing all over on. I'm LIVID. LIVID!!!!! IVE NEVER FELT SO UPSET IN MY DAMN LIFE. Not only am I in pain and can't eat. If I get covid again I probably won't eat at all because it will hurt and I'll fucking die. Great. Fucking great. Cuz I almost died the last time for real.
