This "amazement" at borrowing and debt levels is one of the standard rightwing tropes that emerges from time to time before they slam the poor with austerity claiming it's about controlling public finances. For context, the UK's current GDP is around 3T. In your language that's GBP 3,000,000M. Does 17,400M GBP now seem that big? I think not.
A few other things that seem missing in your picture. The UK economy is not (as Thathcer said) like a household. The National Debt never has to be repaid. That is a crass oft-peddled misunderstanding of the macroeconomy. Debt has to be serviced sustainably to maintain confidence in the currency but the debt can revolve forever. Effectively it means the UK has to cover its interest payments so the ROW is confident it will continue to do so and carry on buying its debt instruments.
