Congrats hun, this is a good move

With the CC, I had a huge debt on it and knew all the numbers off by heart - so I ordered a new card, and froze it into a block of ice and kept it in the back of the freezer. Meant I really had to make an effort if I wanted / needed it to use!!!!!!

As you use your CC for everything now, doing up a budget should be fairly easy in that you can see how much your bills have been for the last year. Do up a spreadsheet with the total spend of everything over the past year - that will tell you what you're currently spending. Now divide each item into how ever often you get paid - for me, it was 26 cause I get paid fortnightly. I then put that amount into an account separate from everything else, and set up all my bills to direct debit to that account only. Include your CC on that list and make the minimum payment on your budget - that will cover the interest and you won't increase the debt. It will allow you some breathing space if needed.

For groceries, read your local junk mail and stock up on basics when they are on special. My DH wanted to go and see how much money we could save on groceries. We just did a fortnightly shop at 3 stores - NQR (not quite right), Aldi & woolies. We bought around 75% of the stuff at NQR and it cost us $38 - it's good for basics and tinned / jarred stuff where short-dates don't mean much. Stuff like cream you can freeze. I did some more of the shop at Aldi but didn't find it had what I was after, which was weird, but I did get meat there a lot cheaper than Woolies. . And the balance at Woolies came to close on $120. All up our shop for the fortnight cost $200 instead of $270. Menu planning is key though, and cooking from scratch saves so much money - stir-through jars cost a lot, as do packet things like mexican meals. Don't be afraid to ask for a sub-total when shopping, and when you're at the big shops that have the subtotal displayed as it scans, put the expensive must-haves at the front of your shop for scanning and keep an eye on the scanner. That way you can adjust your other items and remove any luxuries if $$$ are tight.

I've found it very difficult to budget, and when I started I had a good friend come round every fortnight and help me plan for the fortnight ahead, she really taught me a lot.

Good luck.
