But you could say the same about anything scary... impending loss of a loved one "What's the point in worrying about it?" Yet no one takes this attitude then.
If someone you love is either terminally ill then yes you worry you panic and you grieve.
If someone is taken suddenly you don't because clearly you don't know what is to come.
I am slightly concerned that Putin is backed into a corner and crazy enough to try BUT I remind myself that there is no great Russian state if he nukes half the world.
In all likelihood I am more worried that he will cause a nuclear reaction in a Ukrainian Nuclear plant in a if I can't have them no-one can attitude (not for me clearly but for the people in Ukraine).
I read someone that whilst Russia has very strong Nuclear capabilites he can't nuke the whole of Nato at same time but they could easily take out the whole of Russia (I feel for Russians who are also probably petrified).
None of that is really based on any fact, these are just things that I let myself feel if I start to panic.
My DM died suddenly of a heart attack 4 years ago, it was a massive shock. I do not worry that the same could happen to my dad (clearly it could) because I can not do anything about it if it was and I don't think I could live my life in a state of impending doom or fear of what if's.
