I’ve been a bit scared with my health lately- my heart rate randomly increases even when I’m just sitting or drawing, I nearly black out whenever I get up, I can barely do anything related to exercise because it feels like I’m going to have a heart attack, my heart feels like it jumping around in my chest at random times, it pumps really hard sometimes for no reason, I get really sweaty easily, my ears ring, I woke up one time in my sleep due to chest pain, what is this????? I’m scared to tell my family because I don’t want them to worry but it’s getting worse and it’s really scaring me. Does anyone here know what this is?????
