Wreck you are completely not shit, you are trying to make the best of an awful situation which was not caused by you. Please, please take some of the advice on here and ask around to see if anyone can help you, and do approach your union for help - you don't have to be a member. Are there any grants you could apply for? Have a look at grants-search.turn2us.org.uk/
That would drive me insane too Greyhound - if you can do try not having as much cash on you/ hiding it! - I am very much a cards person but do find that only having cash helps me keep better track of spending. As you know I'm a SAHM so can't really moan that DP doesn't share costs, but it does very much annoy me that when I go out maybe once a month to meet friends for a coffee, he'll complain that I'm spending £5..... then he goes down the pub at least once a week and spends £££ 
sportinguista you can often pick up breadmakers for £10 on Facebook/ ebay/ local charity shops which also sell furniture (I have my eye on one at the moment!)
£10.89 spend for me today, £8 on a music group which the DC were little horrors at, £2.89 at Sainsburys where DS2 threw an enormous tantrum
can you tell it's been a challenging day?!
