How do I get rid of this girl?

About 6 months ago, I broke up with my girlfriend because she was being really controlling and mean towards me all the time, to the point that I couldn't take her trying to put herself above me (we're in high school). Turns out it's actually made some aspects of my life even worse. She actively stalked me for a while, despite a number of restraining orders and parental surveillance, usually online and frequently in school. For about a month after I dumped her she kept trying to corner me and would insist that we were not over, since she had never accepted my dumping her. When she finally got over that, she tried to trash my reputation, which luckily failed completely, to the point that she ended up inadvertently sending her own public standing down the drain. That lasted about a month and a half, then she went totally psychotic. As in, borderline bipolar. When we passed in the hall she would sometimes start yelling and screaming at me (happened 3 times in the space of 3 months), and even tried to start a fight with a girl I was talking to on the way to a class we had together. A couple times she just collapsed in tears in the hallway, even when I wasn't around. This all died down to just some minor stalker tendencies about a month ago. It hit the breaking point a few nights ago. I was woken up at around 12:30-ish when I heard a loud thump followed by a crash like glass shattering from my window, followed shortly by this girl CLIMBING IN MY SECOND FLOOR WINDOW. Within a few seconds my Labrador had burst into the room and tackled her, and she wasn't carrying any kind of weapon, so she wasn't really a threat. I called the cops, and they took her away (she'll do time in juvie), but now she's trying to sue me for supposed "injuries" she sustained from my dog defending me and has expressed in no uncertain terms that she's going to come after me again after she gets out. How am I supposed to deal with this? Thanks in advance for your feedback.
