Hello and welcome. Follow the link that Niobe has given and have a chat with one or two of the companies listed. The advice is free at this stage and without obligation.
The preferred solution will depend upon, amongst other things, the level of disposable income you will be able to offer, the firms mentioned can arrive at this figure with you.
That level of debt will usually preclude a debt management plan, unless you have a high DI. So you could be looking at the choice between an IVA and bankruptcy (as you no longer have assets -- the house-- to protect, and as long as your employment doesn't preclude this, BR is still an option).
Chat to a couple of companies to compare advice and to see who you gel with. Also have a look around the forum where you can glean from our ramblings what we feel about our own choices

My opinions are merely that .. opinions based on experience. Always seek professional advice.
