19 y/o F, 2 days ago I think I had my first episode of anxiety, couldn’t sleep all night, I could feel my heart racing, pounding , in my head and in my neck. And it just started very abruptly. I’m pretty healthy, normal bmi, indulge in moderate exercise, even then these heart palpitation episodes last for days. I’m currently going through one, it started last night and my heart hasn’t stopped Pounding since then. When I check my heart rate it’s within the normal range but the pounding just won’t go away. I know it’s all in my head and even then I’m not able to do anything to stop it. I hate feeling this way.
