I'm sorry to hear your news.
Unfortuately this is the way - assuming it is kids - that this country is going. The people who do this have no regard at all for anyone else and just do what they want to do.
I have dealt with my fair share of burglary victims - it is the "simple" violation that is enough - you could understand if they broke in and actually stole things, but to "just" trash the place seems so completely pointless.
My advice would be to stay strong and positive - be wary for the next few weeks, and offenders often revisit the scene to steal the stuff replaced on the insurance - but try to get back to "normal" or a new kind of normal as soon as you can.
You can get crime prevention advice from your local police office - they should have a "specialist" on the subject who can advise you on alarms, door locks etc
If you live the rest of your life fearing the worst then the offenders will have one.. DO NOT LET THEM GET THE BETTER OF YOU.
No-one has the right to make you feel unsafe in your own home - take control of the situation and MAKE yourself feel positive.
I'm not saying it will be easy, you would expect to feel unsetttled for some time.
When I speak to victims my advice (whether they take it is up to them) is to learn to deal with it, accept something horrible has happened, and then put the experience away in a "mental box at the back of the cupboard" - you know the box is there and you know what's in the box, but it doesnt affect your daily life. You can get the box out as often as you need to, but eventually the box will get put, subconciously(sp?) in the loft, and then thrown out with the rubbish.
I wish you all the best
and remember - do NOT let these little whatsits get the better of you.
(PS You would not want to hear my views of the courts system... (dealing with them on a daily basis) a week wouldnt be long enough....)
