Not knowing what "relatively young" means exactly, I suspect you are still a minor (under 18) living at home with your parents (as you've said). Fr. David has given you excellent guidance. I suspect your own parish priest would say exactly the same thing.
What does "love your family" look like? If I may take the liberty of unpacking Fr. David's words, it is to do your best to be obedient to your parents and the rules they have in your home. If they ask you to clean your bedroom, do so with as little (or better yet-no) complaint as possible. Better yet, keep it clean (make the bed, dust once a week, etc.) so they don't need to ask. Clear the dinner table. Keep curfew, if you have one. Or better yet, get home 5 minutes before curfew. Call them to let them know where you are when you are out with friends. Stay on top of class assignments. Do your best at your school work. And when they do something that seems unreasonable or makes you angry, sit down and talk with them about it. Explain your thoughts about it. It may not change their mind, but it will show them that you want to be cooperative but also have your own opinion of things.
You may already do most, if not all, of these things. But I just thought I'd throw this stuff out there as food for thought.
