You might be getting fatigued but I've not seen any evidence that western governments might. Support has been consistently increasing and most are ramping up their military capabilities to counter this new threat. I don't think there is anything to worry about here.
I'm also not worried about Russia taking tiny fractions of land around Bakhmut, this is the comment that makes it sound like you might be a bit susceptible to Russian propaganda. They are doing their best to make these gains sound like some sort of huge victory. Despite everything Russia has thrown at this small town for the past six months, at incredible cost, Bakhmut still holds. So I find it quite laughable anyone can suggest this area as evidence Russia has the momentum.
I'd suggest if anything has control of the momentum, its the weather. I did hope to see some offensives on frozen ground but that's not happening. Maybe its because Ukraine doesn't have the capability, maybe because Russia has adapted and re-organised properly or maybe it is just the weather, we can't know either way. What I do know is that Ukraine isn't taking its land back 1km at a time, it will degrade Russia's ability to fight in an entire area, then push in hard, forcing a general retreat. It appears right now that things are very much gearing (literally) up for the Spring.
They have also shown they are willing to give up ground if that's what is needed to keep the attrition rate in their favour and from everything we've seen, from both sides, the attrition rate is well in their favour. They might well be losing 3 digit numbers per day but from the figures Ukraine and the US are putting out Russia is losing almost 4 digits per day.
