Hi OP,
Nobody here could possibly help you without seeing your SOA, which is obviously very personal. If you feel up to it then post it, if not, then don't. Or, you do an incoming and outgoing list and scrutinise the hell out of it.
The only thing I can say (without figures) is that sometimes we need to make some sacrifices to the way that we live now, in order to get through the shitty times.
I've had to do this at times in my life, getting a mortgage is one example. That was a choice I made though. What we are seeing now is not a choice we have made, it has been forced upon us, and it is fucking frustrating. I can't even begin to imagine how some people will be feeling.
Some personal tips I've discovered along the way:
Eat less meat - I'm actually vegan for ethical reasons, but I haven't always been. Cutting out meat prior to my decision to go vegan saved quite a lot of money. I substituted meat for lentils in things like lasagne, bolognaise, chilli and who doesn't love a daal.
Bulk cook - If you can, buy more, cook it all and freeze. It's not only financially better, it is less time consuming.
Cancel any dds you don't use often - Amazon Prime, Netflix and the Gym. Absolutely don't if you get your moneys worth.
I'm not in a situation where I need to worry about these things anymore, but my mindset has changed over the years. I don't mean to sound tone deaf, but I can now afford to not worry about rising energy bills, I can buy new things, I can go on nice holidays and I can buy designer clothes. I don't choose to do any of those things though. I don't care about having the newest car on my drive (2004), I'm more than happy to holiday in the UK, I couldn't even begin to bother about fashion/labels anymore and I certainly will be cutting back on my energy usage because I can't stand to think that many children and elderly people will be so cold whilst I'm toasty and warm. It isn't self-flagellation, it's about knowing I don't need to keep up appearances and I can't help thinking about others. I will also do my best to help others.
