Not easy, is it?
Lots of good advice on here.
I'd add to some of it by suggesting you try to work out what gives you the best improvement to your quality of life per pound spent, and prioritise spending your limited spare money on those things (not forgetting the other members of your household!) Let the other things fall by the wayside for now, and see if you can pick them up again later. (Obviously, it helps if you all like some of the same things...)
For me, it's doing and seeing things, and going places - mostly with my family, but a little bit of "me time" now and then (and the opportunity for my wife to have the same). Our car has to last, we don't have an expensive house, holidays are rarely abroad and often camping. I don't feel the need for as many 'big trips' when I'm managing to make good use of the weekends. We lose out on getting new cars, new clothes and kit, foreign holidays, and eating out - I'd like more of these things, but they don't make our lives as much better as getting out and about. You may differ, so work out what's best for you.
Some other tricks that may or may not help - you don't need a TV or TV license if you're happy watching the wealth of freely available content on your computer (legally, nothing as it's being shown on terrestrial TV unless you have a license.) A Netflix or Amazon Prime subscription legitimately gets you more films and TV that you'll be able to watch, for less than a license, too.
If you don't already, see what you can buy second hand or get as cast-offs - we've saved a huge amount on kids clothes this way, in particular.
You're probably spending more than you think on food and drink, and can probably reduce this significantly by being more organised about it. Unless you don't want to, if this is one of your priorities, of course!
Where do you shop for groceries? If you use supermarkets, you can probably save a fair bit without losing quality by going somewhere like LIDL or Aldi first to get what you can, then somewhere else for the rest of your shopping.
