How to gain my parents trust?

Look I am the same way, 15, parents are crazy superstitious, but you need to sit them down and tell them look mom dad I need some independence im in high school and I know you do these things to protect me but tell me some things I can do with my friends that is ok and unsupervised. They will tell and just compromise and that will show them you are willing to work which in return will add more independence, it worked for me, it will work for you
