I m 14 almost 3 weeks ago, I couldn t even get up from bed because when I did I would feel like vomiting and i would feel like it was hard to breathe. It s gotten better over the few weeks but I feel like it s not fully gone and It s weird because It s different pain most of the time, sometimes it s pain in the top of the jaw, my stomach, my arm. It goes away and it comes back, to be honest I was so scared I thought I was going to have a heart attack or a heart problem but I don t know and I m really scared.. Most of the time I feel like its hard to breathe. What should I do??? I also went to the doctors 2 weeks ago and she said I had a heartburn (but I don t actually) so going to the doctor won t help I think.
