Hi Phil
Agree with all the comments above.
Just to add my thoughts. This headline also scared me. But if you look beyond the headlines, what they mean when they say some are referring to ww3 having already begun, is the ongoing conflict with Russia since 2014. Encompassing the initial annex of crimea, cyber attacks, incursion near uk air space, Salisbury poisonings etc….
There are no “experts” worth listening to that are so far peddling the idea that military confrontation with Russia is inevitable. Far from it in fact. The facts are that nato is trying to stay out of Russia way.
Keep calm and get some help for your anxiety. We will be fine.
