I think that you have had your confidence knocked from the off. Give it time & it will come back.
It could be that you are tensing up when coming into bends, I do it every time it's wet because whenever I have come off it's been in the wet. I know I'm doing it, but can't help it & it makes me a cr@p wet weather rider. It is just down to a lack of confidence.
Keep with it & it will come back to you
