My parents won’t let me wear Hijab, any advice?

Hello guys I am a teenager girl. I have only recently started being religious and really want to wear hijab. However my mother said she does not want me wearing hijab because she is afraid I will take it off when I’m older or I’ll play around with it and take it off. I honestly feel like crying because I just quickly asked her “ would you let me wear hijab” and she said no, I wouldn’t. I know it’s a very big sin to take off your hijab and I would never do that. My mom is not that religious herself either but I really want to feel closer to my religion. Can anyone give me advice or how I can convince my parents to let me wear hijab because I really really want to wear hijab. Thank you guys very much!!!
