Urgh op I could have written your post. So far I have done:
I am keeping track on a budgeting app, long gone are coffees out, meals out, treats and days out. All the subscriptions are gone.
I'm having some success with approved foods, it's worth a look.
I've done short, cold washes on everything I can, I have no tumble drier. The heating never goes about 17c.
Still can't make ends meet month to month.
All the kids (outgrown) stuff goes on vinted to make credit for more vinted stuff in the next size.
I prioritise the DC meals (multiple allergy house) and I don't drink, eat meat, non smoker, I DIY my beauty stuff and now I'm going to have to forgo my highlights, even though it was only 3 times a year.
Shopping at Aldi most of the time, no little extras, no flowers etc, even the daffodils for £1 😓
No phone contract, SIM only.
Try and walk as much as possible.
I am constantly trying to work the budget numbers fit and just as I do something goes up and it wipes out any efforts I've made
It's a bit shit.
