Either you're really a total brat... or you're not a total brat, and you're saying you are because you don't like the idea that your behavior's really out of control.
It's a nice little excuse, to say "I totally meant to do that". It lets you pretend that you're defiant and rebellious and don't have a problem you need to deal with.
If you're being a brat, you need to stop it. It's not impressive bragging about how many things you punched to people on an internet forum.
If you're in denial, you need to stop it. Things are never going to get any better if you don't admit to yourself that you have a problem. Think of the addict who says, "Hey, I can stop anytime I want to... I just don't want to." You're doing that. Quit it. You do have a problem. It might be nice to ignore it and pretend there's no problem and you're just a brat, but you're not going to get anywhere in your life if you don't face facts and start working on it.
