What actually happens if you fail 12 boards ?

Qualifications - I am a PCM student, with physical education as my extra subject in CBSE board.

I feel like I'm going to fail in class 12, and the thought of it is overwhelming. It feels like everything I've worked for is slipping away, and if I don’t pass, will that mean my life is over? Will I never get into a good university? Everyone around me seems to have their future figured out, while I’m stuck worrying about whether I’ll even make it through. The pressure is unbearable, and I can’t shake the fear that one failure will define the rest of my life. But deep down, I also know that failing isn’t the end. I know my parents are going to kill me and everyone is going taunt me,but my main concern is what will happen if I actually fail , Will my dream be over?Even if I repeat the entire year ? I think I have failed everybody and mostly myself. Can someone share there experience. Sorry for the rant. 🙏
