It’s good to stay informed but try not to let it impact your day to day mental health. Consider that we’ve been under threat of mass nuclear war for about 80+ years now and haven’t been in a full scale one yet.

There’s little that you’re able to actually influence so as ignorant as it may sound, try to avoid worrying about it. If it happens, it happens, you won’t feel better for having worried about it and there isn’t much you could plan for anyway.

Focus on the things and people that matter to you and take each day as it comes on the basis that nuclear war is not happening.
