Whats the most likely thing thats going to happen?

I'm uming you mean you started off in juvenile court. Do you have an attorney? If you cannot afford one, the court will appoint one for you free of charge. You need an attorney who will fight to get you back into the juvenile system. If they charge you as an adult, you are going to prison for a long time. You didn't give your state and laws vary by state. Your criminal history will play a large part in your sentencing. You need an attorney willing to fight for you. Sounds like you admitted a lot of things to the cops when you should NOT have been talking to them.
