Cut back hard now - when the weather is set fair and there are no hard frosts due. Then feed the plant with growmore or pelleted manure to help it recover and keep it well watered if we have a dry spell (I know the ground is sodden but at the base of the plant where it has been covered with foliage for so long, it could well be dry and you want the fertiliser to be activated to help support good growth). Hopefully it should recover quickly. If any hard frosts are forecast when the new growth is beginning to show - throw an old curtain, sheet or the like over the top (depending on the size - don't know how much you have got) to protect the new growth and remove in the morning.
