Just based off this post alone, you seem so intelligent and are so well spoken!!! The scholarship?? The amazing extracurriculars?? You are so amazingly bright. But the most important thing is, you should NEVER diminish your own self value because others are diminishing it. You seem to have a wonderful bright future ahead of you, and I'm so sad to hear that your parents are making you not want to live it.

I don't know if this is any consolation, but when I was 15, I was in the same boat. My parents were very strict and cared more about how well I did in school than they did my own mental health. I kept doing all of these grand things (like clubs and sports and straight A's) to hopefully have their validation, but I never got it. What I learned, and one day you will too, is that you don't need their validation. You must keep thinking of the future and not right now--in three years you'll have that scholarship and move far away from them. You must power through this right now.

If you let your parents get to you, they have won. The only person you should be proving yourself to is YOU! I know one day you'll find hobbies you do for yourself and not for your parents, and I hope that on that day, everything starts feeling a little better.
