I get tired easily and my heart beats around 100 beats at rest. I get tired very easily. I’m not out of shape. I excercise 5 times a week and i have always gotten tired easily. I get so tired that I feel like falling over. I also sweat way more than I’m supposed to. I’m also 14. My dad has the same problem. Do I have heart problems? Should I go get checked out? Thank you.
