Scared for echocardiogram resultsšŸ˜­

So Iā€™ve had a fast heart rate ever since I had covid and today I finally got an echocardiogram I was really anxious all week for it, but convinced myself I would calm down once it was time to get it but I literally couldnā€™t my heart was beating so fast and I was shaking while waiting for the nurse. I tried to keep calm during our conversation but I couldnā€™t help but look at the screen and try to read her face for any expressions of concern. What if the results were bad and thatā€™s why she was having so much conversation with me so I wouldnā€™t look. When we were done I asked how long for the results and she told me about a week, and now Iā€™m freaking out even more because I thought the results would be instant and now I have to wait a week to find out if something is wrong. I asked her if thereā€™s anything she can tell me and told her Iā€™m really anxious, but she told me she couldnā€™t tell me anything and said ā€œI wouldnā€™t worry too muchā€ but I feel like if it was good news she wouldā€™ve just said she wouldnā€™t worry šŸ˜­šŸ˜­. After the appointment I tried to hold back tears the whole way home while my bf drove and then I just cried in the shower and I canā€™t stop crying because Iā€™m scared something is wrong šŸ˜­šŸ˜­šŸ˜­ Iā€™ve been watching echocardiogram videos trying to compare something to mine from what I remember , but I canā€™t find anything Iā€™ve been looking up normal vs abnormal pictures but honestly nothing will help since I donā€™t know what Iā€™m looking for. Iā€™m just really scared Iā€™m only 21 I donā€™t want life changing bad news. Has anyone else had an echocardiogram for a fast heart rate? What was wrong? Please somebody just help give me peace of mindšŸ˜­
