Should I find someone to take me to urgent care or the doctor?

This morning when I was running up the stairs I heard something funny in my chest. It sounded like my heart suddenly turned into liquid. I only have my usual chest pains, which the doctor already said is nothing. If I talk to my parents they'll say I'm just being a hypochondriac and refuse to let me see the doctor. I might be able to find someone to take me to the doctor or urgent care (I can't drive)?

I have a small hole in my heart, but I was told that it's nothing. No exercise restrictions or anything. I was cleared by a cardiologist as an infant.

Is it serious enough to go to the emergency room?
