I think a priest would tell you to obey your parents and dispense you from the obligation but that is pure conjecture. I’m a 47 year old altar server, what the heck do I know?
I’d bring it up with a priest. Unfortunately, 1:00 AM Sunday is probably a bit late to call the parish office and ask to speak to Father.
The real question is, why your parents are not wanting anyone to know that they are not going to Mass? If they have a valid reason, could they not get dispensed from the obligation as well? That may not be your issue either.
At a minimum, you are to be congratulated. Most people under 20 (I assume you are a teen) really couldn’t care less about getting to Church. Good for you.
