I've been poor for years. Single parent, MH problems blah blah blah. But a couple of years ago just before the pandemic started I got some counselling that really worked for me, went on to get promoted a few times and now this year am finally on a higher wage so I don't need universal credit any more.
Life still has its stresses. My ex mil is dying, my own parents are not so great, obviously I'm worried about the state of the country. But - and it's taken a good six months to really register this because thinking poor has been a long term habit for me - I no longer have to constantly do sums in my head. I hadn't realised how much I thought about money until I stopped having to do it. And my god it is so liberating. It's like part of my mind is freed up from all the crap that's been occupying it for over ten years. It's ... lovely.
And I think, once you get below a certain level, you're never really quite free, but once you get above it things are better, because at least you don't have to worry about money.
