It's very much a continuum I think - I can see above that some homes were clearly over the line to neglect/abuse, and I can see a lot of similarities (we never had animals in the house thank goodness!) around things like amount/washing of clothes, and there's stuff I'm too embarrassed to share even on an anonymous board, but I wonder what makes the difference from growing up in a fairly chaotic/cluttered house but it not affecting you, and growing up a similar environment and finding it still affecting you (aside from the not having good habits instilled from an early age)
I realised the other morning that growing up we pretty much never had fresh veg - it was all tinned, and fresh fruit (other than apples) was a once a month (or year if something like strawberries) treat.
And that other kids had pyjamas, rather than just sleeping in their pants/t-shirt from that day, or that they would be horrified that I basically slept on bare boards and plaster walls on a couple of bean bags for months once, or that there are bottles of god knows what in my parents bathroom that I remember being there from when I was a child.
There just wasn't money or time for decorating a lot of the time, and certainly not for re-decorating. All our furniture was second hand - sometimes from the newspaper, sometimes from skips or dad's work, or family.
The microwave/hob wasn't sparkling, but it wasn't weeks of built up food - we didn't get sick, there were rules about how long leftovers could be in the fridge before you shouldn't eat them.
But on the other hand, dad built me a bike from bits he acquired (legally, but from talking to people to get old stuff) when I grew out of the one they'd got me for my 6th birthday, but they couldn't afford a new one, and they always made sure that if there was something we really wanted for Christmas, they would find a way to get it (it might not be the real version, it would be second hand or a knockoff, or I'd have to add what money I'd got for a birthday to the pot, but they'd get it).
I wonder if it's that I knew that whatever else, my parents were in it with me too - they didn't have new stuff either, they were trying their best, and we were a team.
