In my opinion, This doesn't define your life.
You've spent 12 years in school, and now they're expecting this one year to decide what you'll do with your life. It doesn't make much sense.
Instead of letting one year define your future, focus on mastering what you're good at. Keep learning, keep improving, and stay up to date with the changing world.
There are still many people who believe in you and are hoping to see you succeed.
