Hi Stargirl,
You are already way ahead of your peers by asking others for support.
One of the biggest things you will discover on this site...and it applies here is doing what you enjoy.
I remember being in high school and everyone telling me that I need to start taking courses to prepare for college....so that I could get a real job.
At the time I really loved to draw, however began focusing on a curriculum others felt was "right" for me. I focused on careers based on income and not doing what I enjoyed.
This was a major mistake. The financial impact and more importantly the lack of fulfillment with this approach is a very costly price to pay.
Stargirl...you will do great. Take subjects you are interested in and enjoy, and also keep an open mind. What you choose to pursue today can change...so be open to that.
Don't feel like you have to determine your entire life on this one decision, you can always make adjustments along the way.
Wish you the best!
