My mind is unstable and my heart is being crushed.

Last night, I decided to make one of the dumbest decisions of my life. It all started when my girlfriend of almost 5 months kept telling me her Exboyfriend was harrassing her and she wanted him hurt. I did too but I didn't want to get too involved and I told her to simply ignore him and that violence wasn't exactly necessary but his harrasement progressed. However, one night we decided to call him out to a nearby park and I got in a fight with him and his mom called the cops. They went to my house and even went to my girlfriend's house to find us and arrested us for assault and threats. I was at the police station for hours and I was told I have to get lawyer since they are pressing charges against me and since I'm 17, theres some special rules for me. My girlfriend is also accussed of doing the same but I strongly believe that if we go to court, she will have no charges and no record garunteed since she didn't directly do anything. Even then the text messages used for the meet up weren't threatening at all. I luckily didn't send any text messages since I my phone can't send them anyways. While I was sitting in the holding cell, I could hear my girlfriend crying and her dad came in so did mine and I felt so shameful. I kind of knew in the back of my head that something like this would happen but I was just hoping it didn't. Worse case scenario happened and I'm not allowed to contact my girlfriend at all and visit. Our relationship is in shambles right now and I've been worried sick about her. I love her a lot and I've even gone as far as do this for her but I still get her in trouble. I really don't want to get her involved in this but whats done is done. I don't know what to do next. Contacting her is going to be hard and court is ahead of me but funily enough, thats the least of my problems right now. I'm worried sick about her. All I want to do is just talk to her to make sure shes okay. I can't even start to forget about her. I love her so much that I really don't want anything to happen to her but everyone else is telling me to worry for myself first and not to let this get to my head since they think I'll win the case anyways. Can SOMEONE PLEASE help me?

Timpon, you really care about your girlfriend. She will have to see that and appreciate you and your feelings. I'm sure she's worried about you too.
