Well, you deserve an answer regarding your economic question for the way. Russias economy is doing pretty well, its government used the time from 2014 onwards to create alternatives to western markets. For example gas and oil go to India(who resells some to the EU) and China now. And the US who, of course, does not comply with the sanctions. Another factor of Russias resilience to western sanctions is the historical fact that the west sanctions non-western countries all the time. This created a situation in which most of the world is under western sanctions of varous kinds, the sanctioned countries are less inclined to follow western dictates regarding Russia. So Russia still can trade with most of the world.

Meanwhile Europe did expect to get cheap gas as always no matter how much it antagonized Russia. Unfortunately for them, Russia did not renew the delivery contract it had with the EU countries(which would guarantee delivery for a pre-settled price). Leading to the EU having to buy Russian gas on the spot market (highly variable prices). Some EU countries did not antagonize Russia as much, and thus had their contract renewed, thney got fucked another way by big daddy Washington. With the US blowing up Northstream 2 and Ukraine stopping transit over its territory, the EU is physically cut off from Russian gas and and has to find alternatives fast.

One adress was Qatar, who can not cover the demand. Another was the US, who can but wants multiple times what Russia demanded. Furthermore, in either case the delivery would happen in liquified form. Which is ecologically problematic to say the least.

Liquidification requires lots of energie and produces a shitload of CO2 emissions. Driving it over by special ships (of which not enough exist) again pumps lots of CO2 out and poisons the oceans because the large ship machines are using the absolute worst for fuel. That stuff then has to get on land, sufficient terminals only existed in Spain, in Germany they had to be built ignoring safety standards, because they were needed asap. The US gas is extracted from shale, as a side effect of shale oil extraction. This process poisons the land and water, leading to tab water being flamable in many parts of the US.

Overall this means rising energy costs in the west, which means less favourable conditions of energy intensive companies. The US solves that way by pulling all restrictions regarding shale oil extraction, digging up Alaska and so on and providing tax incentives for companies moving to the US - in short: They loot their vassal states in Europe.

Europe is fucked. Which, of course, leads to tensions within NATO. Especially as the US wants the euros to shoulder the cost of their occupation now, too. Teh EU countries have already been weakened by austerity and neoliberal politics, now have to pump billions into their militaries. Said money is created via debt on one side, via further cuts on social services on the other, creating internal tensions. Said tensions can be observed by the rise of the far right in every EU country.

Another reason for inter NATO and EU tensions is the fact that the countries in the Eu who did not antagonize Russia, now also are fucked. Because the US and it's ukranian dog blocked direct pipelines.

So put together the situation, the EU got fucked by the US and its own stupidity, Ukraine got fucked by NATO, EU, US and its own stupidity, Russia got away cleanly, the US got away cleanly at the cost of its imperial periphery. Climate Change won big. Humanity lost big.
