Ukrainian S-300 surface to air missile attempting to intercept an incoming Russian cruise missile. Chances are we won't be hearing about it anymore within a week.
Yes, every aspect of the war is concerning, but as a recovering "doomscroller" I've learned that it's best not to freak out when news like that initially surfaces. Try to stay calm and wait for more facts. The worst thing you can do is jump to conclusions and imagine the worst case scenario. If you're anxious about something you'll engage in emotional reasoning, convincing yourself something terrible will happen. Thoughts are not facts!
Hope that helps.
