Welcome to Hubski! There's not enough information for me to give a good answer. If you're just starting out in college, at least in the US, there are prerequisite courses to take that are just general courses. You could start out taking some of those with an art course along with the general courses to see how you fare in it. I like the idea of following your heart, and hopefully you can do some of that, but there might be more things you love once you get to college. If you're just starting out, do you have to make a choice this soon? I wouldn't worry too much about people being better than you at art in the beginning. You could get better over time, or you might find out that you want to keep it as a hobby later. Good luck!
unfortunately, the college i'm attending is not completely only for art students. the majority of students are chinese here, and which is why it makes me even more lack of self confident. i can speak chinese but not as fluent as them, that's why i can feel loneliness in my life, and that's where i started to over-thinking about what to do in the future. i know it is only my 2nd term of college, which means that i still have around a year to attending the real university life.. but well tbh i'm a little perfectionist, and i always plan anything i do before doing something. that's why i started to think whether i'm really fit to be an art student :)
