After an anxiety attack, I had all physical symptoms of anxiety, chest tightness, dizzyness,headaches, nausea, stomach issues since. Went to the GI doctor and was told i have gastritis due to the h pylori but after antibiotics it got eradicated. But I still don't feel good.
Hey
I am the exact same! I was I have gastritis and that was about 2 weeks ago I’m in constant agony from my digestive system! Lost my appetite and losing weight 
I have the same exact symptoms almost every single day if not every day. I have dealt with anxiety for 5 years and it still panics me. I have been recently struggling a lot with the shortness of breath/chest tightness and dizziness almost always. it scares me so much but just know it will pass
