I had someone smash into my car a month ago and had to claim insurance on it as i needed two new doors imported from Japan (it was a bad crash). I don't know if insurance will pay out again so soon after, as i know from experience with insurance companies they aren't too keen on that sort of thing.
Go talk to them. Insurance companies aren't the c*nts we make them out to be, they actually are pretty reasonable when dealing with them face to face.
When I was 17 I had $1700 worth of stuff nicked from my car parked on our driveway. Scum. Nothing I can do but claim insurance, and get an alarm.
Ultimately possessions mean jack in life, it's the people, memories, and experiences that matter. So far they've only stolen possessions, but if you keep hiding away then you'll end up letting them steal what's important, memories and experiences.
Chin up mate, you're much better than these low lives who'll never amount to anywhere near what you will.
