so it all started on December 9th 2021, I got my second does of Pfizer, after waiting 15 minutes after I received my vaccine I got up to leave i then experienced, dizziness, fast heart rate, my vision was blurry, I felt like I couldn’t breathe &amp; like I was going to faint i then had to be wheel chaired out into a seperate room where nurses checked my blood pressure &amp; heart rate, they said that everything was fine and that it could have been a drop in blood sugar levels from not eating or as I was stressed about getting my vaccine before I even walked in as all the stigma around the vaccines at the moment that it could have been a panic attack. Ever since this date I have been stressed out of my mind that something is wrong, I have had multiple ecgs done, heart ultrasound, holter Monitor &amp; blood test and all show my heart is fine and that I am fine, the problem is that I still don’t believe I am fine, I constantly have head pressure, I can’t sleep properly at night without waking up jolting or feeling like I can’t breathe, I have never struggled with any of these symptoms before my vaccine nor have I ever had a panic attack before my vaccine, I find I get most of my symptoms when I leave the house or when I’m by myself. Is it possible that me already having health anxiety before this has triggered my health anxiety to be a panic disorder? I have had about 7 panic attacks since but now I’m scared to leave the house &amp; I always want to rush back home? What does this sound like?
