It is awful but as Madame Zelensky said, we have to put up with it
"when you start counting pennies, we are doing the same and count our casualties"
President Zelensky said rising bills are "painful" but if we don't "stand up to Putin and are willing to lose something, there will be even graver risks"
On his last visit to Ukraine as PM, Boris said,
"We're paying in our energy bills but the people of Ukraine are paying in blood"
We knew, when the war started and we supported Ukraine that the energy bills would go through the roof as we could hardly expect Russia to supply gas to a Europe that is sending weapons to Ukraine.
Nothing has changed except that winter is now here, it's cold and those prices are starting to bite.
I do what other posters have suggested, OP, and also remember what the Zelenskys have said. I'm sure they're cold too and have other worries.
Better to be cold than not support Ukraine.
