Hello there. Hope you are doing good. I would like to tell you that you can opt for withdrawal from you college by completing the formalities as defined by your college rules. An application along with the undertaking by student as well as parents stating the valid reason is required in many colleges. But the formalities may or may not be same for every college. So, it is suggested that you should contact the student affairs department of your college for better information.

I hope you found this answer helpful. Good luck for your future.
