Woah, this is crazy

My gosh, so earlier I was feeling really bad, like I had the flu, but my mom had me go talk to my nutritionalist though I was really anxious and felt chilled/flushed/weak, etc. but after I got in the car, the chills disappeared. And they're gone right now, too. my only issue now is my stomach which is perfectly fine, other than just feeling really tight. I don't know if that's anxiety, or just because I am always focused on my stomach and have been even prior to my first panic attack. My throat also feels thick. If that makes sense. Anyone got any good ideas on how to accept this as anxiety? Sometimes I can but then I observe it as someone else and nearly panic thinking that no normal person would feel this way and not be concerned. So is that in my head or....?
