My Heart

I want to share something with you, strangers, that I cannot and do not want to tell anyone else. I am a boy of 17 years and for a long time (3-4 years) quite often (every few days) I feel strong, unbearable, a few seconds of pain in the heart. In my free time I play a lot of sports, the rest of the time - I study until I get blue, my dream is to graduate in dentistry / medicine in England and for this purpose I improve my English. I decided that everything was due to the overload I was subjected to and that's why I stopped doing anything for 1 month. No result. Again the same - frequent, very strong daggers. In the evening, when I go to bed, my heart beats so that my chest shakes accordingly - half of my body !!! I regularly feel myself skipping or beating out of rhythm. My grandmother, who was a doctor, died two years ago. 4 months after your 60th birthday! My other grandmother (paternal line) died in 1991. at 55, 5 years. Both - from massive heart attacks. There are over 5 people, close relatives of my parents, who died of a heart attack. My ears regularly squeak, turn black when I stand up and very often I have the feeling that something in me .. stops or .. dies for a while and then starts working from the beginning. Of course, this can't be the heart, but now all this is causing me mental harassment. Grandma was the most lively, positive and ambitious person in the world and she was only 60 ... in seconds! I have the feeling that my heart is worn out, that it is working hard and that I will beat somewhere at any moment. I don't want medical advice, I will die as much as I am told, it just comes to me a little more. I have other problems .. a lot of other problems and this is the "icing on the cake" . Thanks for reading everything!
