Credit Card companies and banks are always keen to get some repayments going - it's easier and cheaper than taking you to court.
Write to each of your creditors.
Grovel, apologise for not taking charge of your debts, and assure them that you are keen to start sorting things out.
Offer them a payment plan you can afford, and make sure you can stick to it.
They may ask for a list of your income and outgoings - be honest with them.
Keep all copies of your letters to them, and from them, in strict order in a file where you can find them easily.
That should start you off on the path to getting things sorted.
You are not alone - and financial institutions seeing you taking charge and being responsible are far more sympathetic than they are to people who ignore them.
