Well, well, well. Mumsnet goes from saving someone's life to denigrating the life of a victim of abuse in the space of 24 hours.
You should be ashamed of yourselves. We workers all pay taxes so that if we were to find ourselves in unfortunate and unexpected circumstances we would have a cushion for a while till we got back on our feet. That is what the benefits system is all about, no? The OP has explained how she came to fall upon hard times. She knows it's temporary and has explained time and time again about things like the necessity of having a car re: her nature of employment and the school situation.
How many times do people cry "Leave the bastard!" on here? Too many to mention. What people who cry that fail to mention is that if that woman manages to get out of that abusive situation she'll be turned upon by the MN benefit bullies at the first opportunity. This is just so shocking! I'm ashamed.
OP, I can understand your worry. Your income will drop and you're wondering how you'll cope with the decrease. Haven't we ALL gone through the exact same thing at some time in our lives, people?! Have some empathy! Well done to the people giving real practical advice on what the OP can do to save money and calm her fears that she can't manage on her budget.
There is a lot of misplaced anger on this thread. "I work full time as a single parent and am on the same or less." Etc etc. Well, why aren't you up in arms about stagnating wages?!? Public sector workers having little or no cost of living Payrise for years on end are what has made YOUR budget on a full time wage so impossible. Or zero hours contracts! SAVE your misplaced anger and fight against those parts of modern working society which results in thousands of people to fall into the "working poor" category. The OP shouldn't be bullied because you are angry at your own situation!
For what it's worth, OP, I earn just under 23k working full time (less about 6 weeks a year). I have 2 kids and a DH who earns more, who pays most of our bills. So if he suddenly ceased to exist in our lives, we would be up shit creek. I added up our basic household expenses to see if we could manage on just my salary. With 2 kids. It would be bloody hard. No money for clothes or birthdays/presents.
So, OP, hang in there. You have fallen on hard times. You will get through this with clever budgeting and plenty of advice from kinder MNers. And eventually you will get your life back to how you want it.
