I have always had heart palpitations since I was kid (I am now 34, female). Also, for most of my adult life I have trouble breathing, where it feels like I can t get a deep enough breath. I breathe slow and deeply through my belly which is what I ve always been told to do. However, when I inhale I get tightness in my throat, lungs, and upper abdomen. It just feels.. Labored. I also am fidgety constantly. When I m sitting it s not as bad but if I m standing, I feel as though I have to keep moving slightly, even if it s just swaying from side to side slowly. If I am still, my heart does more frequent palpitations and I start to feel faint. I have these fidget urges, yet I feel tired all the time and have very low energy. I try to exercise but run out of breath quickly, and I feel like my throat is closing up and I can t get any air. This has just always been how I ve been, but I m wondering if it s something I should worry about.
