Struggling student in need of urgent advice

Bear with me please. I'm currently an economics student in classe prépa (undergraduate programme preparing for b-schools exams) in Morocco and I can either focus on the Moroccan b-schools' entrance exam or the French one. I have already decided to focus on the latter (Moroccan schools are v bad). However, my parents cannot afford the tuition fee for French business schools even with the maximum scholarship. In order for me to study there they need to get into crippling debt (they're already struggling financially) and they still wouldn't afford all of it + cost of living in France, but they still insist on me going to France. What should I do?

I've always been an extremely hardworking and perseverant student who, despite harsh circumstances, wants to attain the highest heights of the business world and change my family's situation, and as an initiation, I want to study in France and hopefully land a job in high finance. I was willing to risk it all to do it. But when I saw my parents already struggling, not only with money but also with some health problems as they're getting older, that's when my brain did a full 180° and began re-evaluating my choices..
