I'm sorry to hear this.
It happened to me about 10 years ago.
I was in the house at the time (town house with 4 floors). They broke in at around 4 in the morning and me and my then partner slept through it all, only to discover what had happened as they made additional noise taking our things when fleeing the property (we were 2 floors above the break in point).
Luckily, they only managed to take non sentimental items - mainly electronic equipment (mobile phones, wallets/purses/TV/stereo - that type of thing). Thankfully my jewellery (I have a lot of inherited pieces) was all in the bedroom.
I won't pretend - it felt bloody awful.
Especially knowing they were in our home as we slept and if they hadn't been so greedy trying to wrestle the TV off the wall we'd have likely not know until we woke up at normal time.
Chilling to know they could have got to our bedroom whilst we were drowsy/asleep and vulnerable.
We spent the next few weeks waking up a every single odd sound - it was exhausting.
What helped?
Well money and time.
One thing we were told (and I'm sorry this isn't going to help) is that some professional burglars deliberately target the same house a few months later. Why? Well they already know the layout of the house and by then insurance has usually kicked in and they know that instead of the old TV they stole last time, there will be a brand new one.
They get away with it because people don't think lightning will strike twice.
So when I say money, we got a professional safety/security assessment of the home and given we had thought it was pretty secure we're surprised at just how vulnerable the property was.
We invested in a massive security upgrade on alarms, locks, CCTV etc.
The later did actually capture thieves attempting to break in via the same entry point 3 months later but being foiled by all the new measures we'd put in place.
That was was ultimately helped me sleep again - knowing we'd secured the house.
To be clear we lived in a nice area that wasn't known for break ins - the police said we (along with a number of neighbours) had probably been targeted for that very reason.
