I'm a minor and I'm getting birth control without my parents permission
Why don't you want to tell your parents?
I don't want them to know that I'm getting that and that I've been drinking and doing drugs since I was in middle school.
If you don't want to have a child doing that is a smart idea. There are some choices you are making that are wrong, but birth control is a good way to make sure you don't have an unwanted baby.
I should be able to practice safe sex anyway that I want.
It would be nice if you could share what you do with your parents to help keep you safe, but it is a smart decision to be on birth control if you're having sex. Be careful, though, because birth control pills don't prevent against STDs, so you should use a condom if you don't know the history of your sexual partners.
