How do I tell my parents I failed 2 of my major subjects last sem????

I've been hiding this from them for 2 months (the whole summer vacation) but now it's already back to school and I'm shitting everytime I try to tell them about it. For context, I live with them and I'm already in my 2nd year of college. My parents basically got so much expectations from me since I was the "valedictorian" during highschool haha fuck. Tbh honest I don't want to tell them and just want the world to fucking end or something. It's making so stressed right now
