Sorry to hear this and I hope you are ok.
I don't mean to scare you but they may well come back as they may just have had a look around to see whats about. This does happen and they then return all set up to take larger items like your tv or hi-fi or where you keep items like car keys. They will also check to out your security at the same time. Hopefully they don't but this does happen.
Why not secure your garden like outside lights, locked gates, fences with additional trellis work, improved locks on windows and an alarm fitted to the house with a box on the front and rear. Even dumby boxes stop them. if you have a dumby box fitted insure you have net curtins up as they look for room sensors.
Make sure anything that can be used outside to climb up is secured like bins and never leave a ladder on show or any garden tools.
If you go out don't just leave a light on, leave a tv going as they can see the light shade change through curtins and that makes them think someone is home along with the sound.
The police may be able to give you info on recommended security companies within your area too.
Burglers always aim at easy targets, make life hard for them.
