Hello,

All the preferred career choices you mentioned are totally different from each other in the sense fashion designing is good for those with an artistic talent, to pursue a career in psychology it's important to have a natural liking towards helping people, and being empathy is one of the required trait, and a career in nutrition is focused on a knowing more about in-depth aspect of food and healthier ways to live free from any illness and  people too in recent times have become extremely health conscious, and all the three field you have  mentioned are quite different from one another, since you're yet to start your 12th, there is more and one year in order to decide your career, take your time and perhaps discuss with your parents regarding the choices, I would say if your passion is fashion designing then focus on it whole-heartedly, since you mentioned it in the top-list, the courses you mentioned are very  different from one another, and it's not like they fall in the same discipline, so as per your strong preference, choose the course, and you can also evaluate the same from the fact that which are all the subjects which you enjoy and at the same time score good marks as well, this can be of the deciding factor.
