Feeling torn about wearing hijab despite my parents' wishes

Salam everyone, I'm really struggling and could use your advice. For the past two years, I've wanted to wear hijab, but it wasn't allowed in my high school. Now that I'm finished and about to start university, I finally see a chance to put it on. Honestly, I miss covering so much. Every time I leave the house without it, I feel incomplete. My main reason is to draw closer to Allah, alongside other personal motivations. But here's the issue: my parents are strongly against it. They're worried about discrimination, me missing out on opportunities (they stress this a lot), thinking I'm not mature enough, pointing out that some people are fighting to ban it, and saying I'm too young (I'm almost 18). My mom cries and begs me to wait another year, but I doubt they'll change their mind by then. I've already waited so long, and I'm tired of going out uncovered. It feels like something is missing, and I just want to embrace this new chapter fully, with my hijab on. Yet, I don't want to hurt my parents or lose their trust. I've also learned that obeying Allah comes before obeying parents in such matters. What can I do? How can I soften their hearts and help them accept my decision? Jazakum Allahu khayran for reading and for any advice. <3
