Or you could take a "gap year" and work for a year, find out
your interests, then get back to studies. You will mature when you
work.
Do not worry, you are not alone. Some in Singapore are also
unsure of their majors. You have to discover your passion and
interests. Try out more new hobbies, meet new people, have fresh
ideas.
Take care.
You are good at some things and talented. It takes time to
discover your sweet spot.
