Hi guys. I'm 17 years old and all I can think about is my chest pain and fearing a heart attack and dying. My doctor said there is no way someone as young as me should be having heart problems unless I've had previous heart problems or I'm doing drugs or if I'm very athletic. I'm none of those, but I can't seem to believe him. My chest pain is constant, so it makes it hard to trust him. What do y'all think?
