if you are grown-up and have sufficient education then ask ALLAH SWT to make you use that knowledge wisely. and explain your parents your commitment, using coherent and concise arguments. Be Genuine, inshaALLAH parents will understand. But dont just Give up. we are made for these test. ALLAH SWT asks us to ask him, cuz He has all the powers. if you really believe he is the one!..pray and pray Hard! if not in this world then inshaALLH in eternal world you will be justly rewarded.
