????Hows this happened???

Hi Guys,
I went on a trip to Cornwall for the week and managed to 'alter' the shape of my board. \it seems to now have quite a channel in the middle just to the right of the center line. The channel is about 60 cm long and must be 2.5cm deep.
I have taken the wax off, applied some cloth over the center line and brushed some resin over where it looked the weakest and got on with it.
Now I am progressing a bit its a huge hindrance, it puts you off balance when you try to stand up, one side of your bum goes in and sends you off balance sat in the line up and when you paddle you have to lie off line a bit to go straight.
How do I fix this? Do I need to cut it all out, add some Qcell and resin to build it up? If I took the top layer of glass off I feel I would need to remove the squashed foam. If I use qcell, how much do i need compared to resin?
Any responses welcome!!
Cheers
Dan
