What can I expect if my first offense is 2 felonies; one 3rd degree and one 2nd degree?

Extra info: The alleged offenses were over approximately 2 years ago, and they JUST sent a warrant for me maybe 3 or 4 weeks ago. The charges are Breaking & Entering + 2nd Degree burglary (Criminal Mischief. $1,000+ of damage). I AM a minor, and this is my first offense. I know that what I did was bad, and I'm not looking for a "You're a retard, Why'd you do that in the first place?" lecture. I just need help, Please! I'm scared out of my mind..
