Hello, I think I suffer bad anxiety. I had a parent pass away in November 2017, I m 25. After a couple months I find myself very concerned about my health. My breathing and heart to be exact. I have shortness of breath, no chest pains, no feel of my heart wanting to beat out of my chest or anything like that. And at night I can generally relax (after using some Vicks vapor rub and fall asleep) My doctor examined me and said he thinks it s just anxiety and did a x-ray of my chest and found nothing wrong but I m just looking for another person s opinion on the situation. I can have normal conversations without feeling the need to stop, I can exercise doing rigorous cardio activity, so I m thinking cause of these factors it should dismiss something being legitimately wrong.
