Dereck Rawson had debts of almost £100,000 on 16 credit cards
The death of Dereck Rawson, 51, has prompted calls for tighter government controls on credit card companies.
The coroner in Huntingdon recorded a verdict of suicide on Mr Rawson who hanged himself at his home in Yaxley, Cambridgeshire.
He wrote a letter to his sister saying he was going to commit suicide and asking for her forgiveness.
The letter to Sheila Wade read: "Please forgive me for what I am about to do and that is to commit suicide.
"I've run up large debts with credit card companies and loans for the last 15 years.
"Now I can't pay the bills and the different companies won't leave me alone. Can you please get the police to come and find me in the bungalow."
The inquest heard his problems began 15 years ago when the sale of his house following the breakdown of his marriage left him with £10,000 in negative equity.
He was able to get more and more credit cards to pay off his existing debt, mostly built up through penalty charges and interest, although his weekly take home pay was just £340.

Ian Richards, a counsellor with the UK Insolvency Helpline, wants credit cards government-regulated to stop people being driven to desperation.
"With credit cards there is no limit to what you can borrow. All they care about it whether the customer is making his minimum repayments."
