What shall I do after this fight?

I got my belly button pierced without my mother knowing, and she found out. My mother told me about 10 years ago that she gave up smoking, but hasn't, and told me she quit her job, when she was fired. Therefore, I feel what I did shouldn't be so serious, when she herself lies frequently. She's now refusing to give me money for anything, and will try to prevent me from going out. (this will not work, as i WILL go out). I'm nearly 16. She also insinuated that I do drugs etc, which i don't at all, and started saying i was exceptionally untrustworthy, because I saved up my dinner money fo the piercing, so she said I wasted it. I think she's being unreasonable.
