Re: Things you do to…
It does as you cannot be busy or occupied 24/7, but when that happens, consciously divert your attention to something, may it be family, hobby, some mundane task/whatever. It’s difficult initially but possible.
Focus on the good things and be thankful for those. And like others’ mentioned: talking to family, praying, reciting some tasbeeh or Allah’s name that gives comfort. If you think this world and everything in it is temporary including us and our worries, it sorta brings peace.
