HELP I REALLY NEED IT READ PLEASE AND TELL ME WHAT YOU THINK WHA CAN I DO?

you are 15. No matter what country you are from every teenager experiences this with their parents. From friends, to boy/girl friends, to curfews, and independance. You can clify yourself as a young adult or whatever, but you are under 18 and that still makes you a child and under the supervision and care of your parents. If they are that strict then you need to sit down and talk to them about what you want to do, why you want to do it, and what you will do for THEM if they allow you to do it. If you want freedom and independance from your parents, you have to show them that you can be responsible with what you are doing, and be responsible for the actions or outcomes.
