Would I lose more weight on the dukan or eating just raw fruit and vegetables?

I bet you don't look horrendous at all for a start. And losing a lot of weight quickly will lead you to lose muscle and fluid more than actual fat. Do some intense stomach crunches to ease your mind, drink lots of water and buy a lovely sarong to match each bikini and cover your insecurities...as I am pretty sure that insecurity is all you need to cover up.
