Panic attack or something worse?

Not asking for reassurance but just venting…. I have been dealing with vertigo and inner ear issues since November and it has really caused my overall anxiety to flare. Specifically, health anxiety has been a huge challenge for me and I have even been experiencing episodes of derealization and depersonalization. A lot of my anxiety has been related to feeling dizzy and brain fog. I noticed that I felt a little nauseous this morning and on and off throughout the day but was able to eat and get through work. I also got a chiropractic adjustment for it today, which I thought would help my nervous system and anxiety overall.

Later in the afternoon I grabbed tea with a friend and he mentioned he had been sick with diarrhea and vomiting a few days ago….. I tried not to read into it too much because we didn’t share food and tbh is friend is sort of always sick and throwing up anyways….

I was just at my friends house eating dinner and noticed some slight pain in my belly but tried to ignore it. Then a few minutes later I had a huge wave of nausea that came out of nowhere and thought for sure I was going to be sick. I ended up leaving and going home, and now I can’t stop trembling and worrying that the nausea I’ve had all day is a sign that I have noro or something. I’m really panicking and having a hard time telling if this is panic or if I’m getting sick
