OP the internet is not necessarily much of a friend to you at the moment, if reading and watching stuff is getting to you. It's your choice whether or not you keep exposing yourself to sites like twitter, where quite frankly there is some hysteria generated by various academics and ex-military and ex-government talking heads who see this as their 'hour on the stage' and want to be 'right' - even when being right in their doomy forecasts would mean terrifying widespread nuclear war 
Some people who spout off on social media wouldn't be out of place in a death cult, although many of them don't realise that's how they come across. You've got people daily proclaiming how they can't stand by a moment longer and watch the slaughter and their/our government should. fucking. get. in. there. But are any of them upping sticks to fight the good fight, whether it be volunteering on the front lines or parking themselves indefinitely outside a parliament building until. something. is. fucking. done? In the vast majority of cases, nope. Those people just like to see themselves typing stuff recommending what others should do to stop any more of the bloodshed happening, while knowing it won't stop just because they say it, but it sounds heroic to say it. Stuff like that. So easy to be a keyboard warrior. And that's part of what you're reading and reacting to at the moment. A lot of bullshit, quite honestly.
Just on one MN thread I've seen people 'significantly' second guessing why flight tracking software was showing various Russian private jets flying to far flung places, or changing course midway to China and heading back to Russia. This was a couple of weeks ago. At that point, some people were reading that discussion and concluding that it probably had something to do with nuclear war and the 'red button'. Two weeks later, we're all still here.
I've read the gamut of armchair commentary, from "Putin is about to nuke us, imminently!" to "it's very possible Russia's nuclear capacity is now very diminished compared to Cold War days and they're just bluffing". I mean, which is it? Oh, that's right, you don't actually know 
We're also seeing lots of people posting things like "Putin has only just started, his agenda is to completely dominate Ukraine and then go for here and here and here and here..." How the fuck does anyone actually know what his intention is? Especially now that there's plenty of evidence to indicate that his Ukraine invasion isn't as successful as he had hoped.
I'm at the point where I acknowledge the tragedy and horror of what Russia is doing to the people of Ukraine day in day out. Beyond that, it's mostly speculation, in many cases dressed up as "I know". In many cases, they don't fucking know, but it won't stop them saying they do
We need to be discerning and notice what's happening with 'commentary', sorting what seems reliably researched and supported by facts from what is hot air and opinion. "If you can keep your head when all about you, others are losing theirs" or something...
