Plese help me I don't want to go to jail!!!?

Okay, so about a year ago. There was a big fight between my sister and my uncle. And my uncle raised his hand to hit her and I pushed him, threatened to **** him up, this and that. (You know how people get when they get angry and black out.) Alright so I got court for that. They gave me supervised probation for 6 months.(They was thinking about 5, but the 5 would've been unsupervised and less money for me to pay and less money they got out of it.) Anyways so then on the way about 6 months later... I picked up another charge for trying to impress my friends. I stole my mom's car. I know I didn't cross wrong lanes. But they hit me with marked lanes, OUI, possession of a dangerous weapon, driving with no seatbelt, and unlicensed operation. So I was in court for that blah dee doo. And I completely forgot about my court case. Now I've been on the run for about two months now, because I know I have two warrants.(For both cases.) Because I missed both the cases, one case was supposed to be dropped which was the probation one. That was a minor offense cause I was going to juvenile court for that. Now that's not my issue. The issue is I missed my adult court date and I'm afraid to go in because I'm scared they will arrest me. I don't want to go to jail, and I don't really know if they're going to hit me with a lot of jail time. Can someone PLEASE tell me if I will get jail time for this? Btw they can't prove the OUI, and the seatbelt thing. Please someone tell me what's the best, and worst possible outcome if I go into court?
