It sucks, OP, I've been there, not in that position any more, but I know it's hugely stressful. I'm not sure if you're after any advice, and some might be obvious, but I'll put it out there in case it helps anyone.
-Check you are getting everything you are entitled to, even single person's council tax etc can make a difference.
-If you are able to be strict with yourself, it is worth arranging credit (e.g. low interest credit card) before you need it. Obviously, you should avoid using it, but if you need it for an emergency it is better to have it prearranged. I think a credit card which you can pay off slowly is less of a vicious cycle than an overdraft, but others may disagree.
-If you can save a small amount of change every day or every week, it does add up and gives you a tiny bit more at the end of the month.
-Do you use any rewards cards? Supermarket points/boots etc can add up!
-Can you do anything to up your income? Budgeting advice is all well and good, but increasingly it's just bills are too high and there's not enough coming in. Even if you just picked up the odd evening babysitting or something, that would give you a little bit more to play with.
But sympathies- it's not that long to go- I'm assuming you get paid on Friday as 5th is a Saturday?
