HELP PLEASE idk what to do

Okay so I'm an 18 year old female who has been to the e.r 3 times because I was very anxious and worried about my heart. The first time I went I did a bunch of tests; x-ray, ekg, blood test, and urine test. My doctor told me 'I was fine' and let me go. But I don't feel fine.. I'm weak most of the time, I feel like I'm not getting enough air or there's insufficiant blood being pumped through me.. and I've been diagnosed with a right heart atrial that the e.r doc didn't even tell me about. When I went back yesterday to ask why I got a borderline ekg, he said it means it was 50/50, not good not bad. There was something wrong.

Sorry to hear you're having so much difficulty.  It sounds as if there is nothing to worry about.  I would recommend finding a doctor you trust and discussing your symptoms to him/her in detail.  I'm not sure what the "right heart atrial" is referring to.  I wouldn't worry about the ECG.  Have your physician explain exactly what it means so he/she can put you at ease.  Best of luck.

First, stay calm. Fretting will make you worse. Then methodically pursue your questions with a cardiologist.  50/50 is not an answer you can accept. Who diagnosed the 'right heart atrial'? did you undersand what he/she meant? Cardiologist or internist?
Keep at it.
