How old are you? from the scenario you described, it seems that you are an introvert. you keep things to yourself. i would advise you to open up a little in front of your parents because they are your best friends. every parent will be in anxiety
when they will learn that their child have some problem, nothing wrong with that. They are the best persons who will understand you and will try to give the best possible treatment.
I will advise you tell the symptoms you are having to your parents and donot panik. Nothing will happen. Behave like a grown up and face the challanges in life..thats what life is. you need to be seen by a physician/ doctor for clinical check up. do not worry...sometimes acidity/ gastritis
can cause chest pain
and these type of symptoms..
Be brave..go for it..tell everything to your parents
