Simple Question; How could I make my mother trust me?

i had the same problem but in the end i found out my mom was just trying to keep me from making the same mistakes she had.. she is trying to protect you she just dont know how because she knows you can do stuff on your own. try sitting her down and tell her you love her and understand she wants you to be safe and know what is right and tell her if she raised you right then you will make the right decisions on your own!
