Overdrafts are evil things so hard to get out of.,
I've been the same in the long distant past, but not the same amount although would be equivalent to around £1000 now.
Eventually I got it sorted but it was bloody hard! And that was when I was earning ok and didn't have a child!
In more recent years I've had to manage on a tight budget and have learned to haggle, get good deals and time purchases for best economy.
I use spreadsheets and soa's and while it's not as busy as it once was the mse site is excellent for tips and tricks, not just the chat forums but many articles on the main site.
I learnt so much from it.
Planning and sticking to a realistic budget really is the key, a bad habit of mine until I learned better ones was making crazy overly strict budgets that were impossible to stick to and didn't take into account things like birthdays, Christmas, summer holidays (dd in school at the time and I'd always forget that her being on fsm meant my food bill went up in holidays, also that not ever doing anything that costs anything even bus fares makes for an incredibly stressful and miserable holiday)
It's like dieting, if you're too strict and deprive yourself too much you'll get fed up and "Rebel"
Yes you need to keep costs down wherever possible but you and your family also need a life.
Stupid that I used to get "caught out" by Christmas, as Martin Lewis says it's every year on the same date it's not a surprise! So now I start saving in January! Not a huge amount, but it does make things easier.
Was particularly hard for me this time of year because dds birthday is just a few weeks after Christmas so I really had to get organised.
Actually to be honest I start saving in January but when dd was school aged what I saved from jan-jun was to cover extra school holiday expenses (and I'm not talking huge luxuries here, just the extra food costs, bus fares to go eg to beach or nicer parks, occasional trips to cinema or swimming, Ice creams from the van...)
And then jun-dec was for Christmas and dds birthday.
It's habit now I have a standing order set up to transfer from current account to savings. So it's just like having another bill.
But I've also spent time over the years shopping around to make sure I keep costs of bills down, I'll challenge a company I'm with if they bump up my bills a lot and I'm not afraid to haggle or even threaten to leave to get a good deal. And I will leave a company if they're taking the piss.
Loyalty is a fallacy in consumer terms, private businesses exist to create profit for their shareholders their only real interest in the customers is how much money they can make from them.
Keep an eye on your direct debits and don't be taken for a mug.
Also check your seemingly smaller expenditures. I'm not really a Starbucks type person but when I am going out and about (currently housebound) I've a bad habit of not making sure I have water on me (meds dry me out) and ending up buying bottles at premium prices - stupid! Doesn't seem a huge cost at the time but it really accumulated over a month/year.
Eg say £1.20 for a bottle of water 4 times a week over a year is almost £250 a year!
An ex colleague was often badly organised with travel fares, she was MUCH better off getting a monthly bus ticket but regularly either forgot to get it or to make sure it was in her bag so sometimes she was effectively paying twice, eventually she hit a really skint period and got herself much more organised and set reminders for herself on her phone and computer at work to both buy it and make sure it was in bag ready each day.
Also (and I still have to remind myself on this one) it's easy to get into a rut buying the same groceries each week, and not taking advantage of special offers but it's good to look for the offers and plan accordingly.
One tip on mse that really made a difference to me was switching down one "brand level" to find products that tasted/worked just as well as the ones you're used to. Martin Lewis was advocating this long before eat/shop well for less came about though they do a similar thing.
I've never been a brand snob as such but I was wary of the budget ranges in the supermarkets but I saw this on mse years ago and gave it a go and found for most things I didn't really notice a difference. Some items weren't a success and I stayed at my usual brand level, levels being:
Named brands
Premium supermarket own
Regular supermarket own
Budget range
The idea is if you normally buy eg premium you try regular, if you're ok with regular you then try and go down to budget and if you still like the quality/taste you're saving good amounts of money but if eg you move from premium to regular and that's fine but upon trying the budget you don't like it you go back to regular but not premium
Sorry bit waffly but hope it makes sense.
Like most people there are certain things I won't compromise on eg fairy liquid but I've also often been pleasantly surprised and been able to make savings.
So yea, budget, shop around, haggle, be a wised up consumer.
