Oh, that just sux! I'm so sorry for you. It's not even so much the money (though that IS an issue) as the time and effort you spent making the bike just right for you. I'm sure your heart just sinks every time you think about it and all the good miles you did together. I've never had a bike stolen but I have had a pretty wonderful guitar stolen, and I think the feelings of loss and sorrow and violation hurt me worse than the monetary loss.
Remember that old saying: when one door closes, another one opens (I'm usually not that sappy, but it seems called for in this situation). Now, on to new things--your new road bike. Sooner than you expected, but hey, life doesn't follow a script.
