Having just recently had some valuable tortoises stolen from us, I can sympathize a little with your situation. It'll take some time to get over the initial shock, and being violated really takes a long time to get over. What's helped me is to attempt to be optimistic, even if it's fake...you know...tell yourself something until you believe it type of thing and don't get bogged down thinking of all the things you should have done. All I can say is that I am sorry, if it's any consolation whatsoever, you are not the first person this has happened too.
