Heart Disease??!!

This few weeks i have been feeling pains at my heart.. I don't know why, I haven't checked to the doctor but I'll check it later if it still continues. My theory is that the heart pain is caused by me eating a lot of oily food but it is still just a theory so I don't know yet if its true or not. What will happen if it is a heart disease? How much longer will I have? I hope that it is not a heart disease.. I still wanna see someone everyday. fuh... ◕‿◕
