I recommend trying to be at peace with the worst case scenario. I.E. I used to worry about people stealing my things while I was asleep but then thought through how I would handle all my things being stolen and how hard it would be for someone to steal all my stuff (i.e. they can't take it all). Once I realised I only needed to replace a few key items which were quite affordable and relatively easy I stopped worrying about it. Not sure if that works for everything but I'd figure the uncertainty is often why we worry. Realising that even in the worst case people will be able to muddle along can be a weight off one's mind.
