This has happened to me as well. Sadly there is always some risk. The only house in my neighbourhood that is 100% safe from thieves is a biker clubhouse, but even they have to worry about police and rival gangs. (I suspect they're more worried than I am).
Minimise your exposure as much as possible, repair the breech in your security (they are going to come back), and try to find a way to come to terms with the fact that living in the world just entails some risk.
Good luck!
We are doing everything that we can to make ourselves safe. I am just overwhelmed at this stage. Am just fed up!
