There's nothing to be ashamed about - there are thousands of people in the same boat as you - at least you are doing someting about it - only reason i am here is because of my debt (under control now thank god).
Best bet is to look at increasing your mortgage by £30k to pay off all the debts - it will be a lot cheaper each month than you are paying at the moment.
if you take out a consolidation loan you will be paying interest on interest as the loan you have already includes all of that interest and then the consolidation loan will add all of their interest at the beginning so your £30k will turn in to say £35K just by taking out the consolidation loan.
if your credit rating is good have you looked at putting whatever you can onto a 0% card - even if it's only for 6 months it can make a real dent.
If none of that works you could look at debt management - it reduces the amount you pay each month but extends the period you repay. Also it relies on the goodwill of your lenders to freeze charges and accept what is offered so if your credit card company are being "difficult" now they could still be in Debt mangement.
Look in your yellow pages for an Insolvency Practitoner near you - they will probably give you loads of free advice on your options and they are qualified unlike so many "debt advisers" out there. Seems almost anyone can advise on debt these days so make sure you speak to some one whose qualifed not just a "debt counsellor"
