As others have said, it is highly unlikely you will be burgled. I believe burglaries have decreased dramatically at the same time as online crime increasing.
However, as you are worried, would it help to have a lock on your own bedroom door and to make sure that you always have a torch and your mobile phone next to you when you go to bed?
I think leaving the radio on downstairs is a good idea too, and, if you are able, having a dog.
Our dog is not at all aggressive but on one occasion for sure and maybe on others his barking has warded off burglars.
