jynier, it is impossible, to be honest. I'm behind in everything, just so that we can eat.
we don't drive, don't go out, don't drink or smoke, don't have subscription tv, don't buy clothes, get hair done or anything like that, don't go trips etc. with kids, kids only have 1 club (BB and GB). There is nothing left to cut back on.
The worst of it is that DH changed jobs about 4 years ago to try to get a more secure salary. The next year the pay freeze came into effect and he hasn't even got the incremental rises that he should have, so his wages are about £4,000 a year short of where they should be. The other problem is that once you take travel to work costs off, he only sees about 40% of his top line - the predicted increments were supposed to take care of that.
On paper, we get a few pounds a month over the cut off for things like housing benefit, but in reality, we have nothing like that.
However, we have a roof over our heads and food in our stomachs, plenty people don't, so in many ways we are blessed.
