so i’m aware that most likely nobody here is a doctor, but my anxiety over cardiac issues is so awful, and i’m needing some advice. i’ve been having this sensation in my chest/throat that feels sorta like the urge to cough? i’m not sure if it’s heart palpitations or something else, but it’s terrifying, and makes my heart race fast. i do have anxiety, ocd and bipolar but this stuff scares me so much. i’m terrified i’m going to go into cardiac arrest, and i guess i’m asking if i should be worried about this? my background is… i’m 17, female, i’m severely overweight but otherwise healthy, my blood pressure is almost always below 120/80 and my cholesterol is 166. i have no family history of heart issues except for my grandfather having a heart attack and heart surgery, and my grandma has heart arrhythmia. do you guys think i should be worried about this kinda stuff? (i’ve also had two normal EKGS besides my pulse being high)
