The first thing you need to do is to give your parents each a huge hug and a thank you for supporting you and your dreams. So few people have that. I showed horses for years and every week would bring home a few trophies. My parents never came to see me and seemed mostly bored with the whole thing when I spoke to them about it. It wasn't there thing.
It sounds like you already know what to do and it sounds like you have the love and support and encouragement of people who love you. Never forget how important that is to have. Good luck to you.
