I had one of my previous cars stolen, stripped and written off and at the time, I thought it was the end of the world. Looking back now, it seems like a distant memory. Even though you'll be thinking 'why do I bother', you will get over it sooner than you think. There will always be 'lowlifes' out there who don't respect what others have worked to attain.
Just remember, we're better than them and as Robin said, don't let them grind you down. Hope you get it all sorted quickly, and remember at the end of the day, it is only a lump of metal!
