To give you an idea of the sort of loan that you could get. Suppose that you have something of value, you could take it to your local pawn broker and get a loan of £3000 with an interest rate of something extortionate like 25% per month (apr 1355%). You would then have to pay interest of £750 per month until you ran out of money. You would then lose your item of value and could also still be held liable for the debt.
If, instead, you offered to pay off your current debts at a rate of £750 per month, your creditors would accept this offer and within a few months your debts would all be paid off.
I appreciate that you are unlikely to be able to afford £750 per month. The point that needs making is that another loan in your present circumstances will make your situation worse.
