A question that is depends on my future

I am currently a grade 12 in ontario. Throughout high school, I have done nothing significant. Barely joined clubs, didnt contribute to my school, nor got good grades. Ive been a bad student every year and have not got any honors. As the end of first semester is approaching and applications due dates are coming, what do I genuienly do with my life. I dont want to take another year in high school. Additionally, I am only doing bad in one course which is economics. I dont need economics for my university programs and idk why I took it in the first place. Besides that single course, I am doing somewhat decent in my other courses. What should I do? I am worried about my future. I really dont want to become a failure and be the "oldest" student in my high school.
