You are obviously intelligent...you have a future. And a bright one.
Being bullied is absolutely horrible. I wish I could come there and protect you from that.
I was never in the "in" crowd in high school. I was never really in ANY crowd. I had a couple of friends and focused on academics, but I did not experience bullying, so I don't really have a full understanding of how much it hurts...but I have some experiences of rejection...and boy does that hurt.

Let me tell you...college can be SO much different than high school. Obviously it depends on where you go and the focus of the school.

What do you want to study in college? There are groups for everything there...people you will find to fit in with. If you're interested in math and science, you will find others who are as well. If you are interested in arts - you will find others. There are so many opportunities for the future. Just hang on. You can make it through.

Do you have a teacher that you feel close to? Someone you can confide in there (in authority) about the bullying? Or another adult in your life if your parents won't listen? A youth group leader or pastor? A friend's parents? A counselor?

edited to add: You mentioned wanting to be a doctor...that's an awesome aspiration. and you can do it...don't let the bullies take you down.
