Well obviously I'm a right weirdo, and some of the comments aimed at me here do have a point.
However, we may get a snapshot of someone else's life here, but that's of course not the whole story. I am not some freewheeling hippy with not a care in the world, I was trying to point out that some things that people consider essential ARE NOT and since the OP is struggling financially I was trying to say that it is possible to make different choices and be potentially better off as a result.
I just don't think that having all these valuables and assets is as important as people make it out to be. I don't live in any kind of student shithole, but I also see no reason to bankcrupt myself by getting a car or a big telly just so I can feel I belong - and I don't think it's an extreme view.
Insurance - maybe I'm missing something here, but I'm not really worried about losing our things - how often does something like that happen, and I am not sitting on some crown jewels! And we're unlikely to be flooded on the 2nd floor - top of the house 
And yes of course I have thought it through, as I said we only get a partial idea of other people's lives from these posts. We're using some savings to get through this year because we thought it'd be better for DH to stay at home for a year than putting our 1yo DD in childcare (and paying a lot for it). It's all been carefully calculated. And we have a nest egg from my mother which is being saved for our daughters' future - but it's also something to fall back on if something went really wrong. And my DH's is entering into a career next year where employment is pretty much certain.
I obviously am quite blinkered when looking at other people's lives and choices from my own quite different perspective, but I think if you are unhappy with your life, and are capable of changing things, it is worth reconsidering your choices and priorities.
