Trev's quite right too. You should be thinking of getting your existing debts under control before you even think about a mortgage. You could get a mortgage that covers some of your debts, in addition to house finance, but it's likely to be expensive and I wouldn't advise it.
Give your local citizen's advice bureau a call, and ask them to put you in touch with a debt counsellor (not your bank, and not a financial advisor, because they're usually biased). A DC can help you to prioritise your debts and negotiate easier payments with your creditors.
Ask yourself, too, where you can make financial cuts in your life. Do you really need that car, or could you get by with something smaller, slightly older? How often you go out? Can you cut back on that at all? Not buy so many clothes, bottles of wine etc etc?
Of course, if you go bankrupt, either self-petitioned or at the instigation of a creditor, you'll most likely not be able to get any credit for at least two years, and often longer than that - whether you declare it on an application form or not (and actually, not declaring it is an offence).
