yeah, this is half of the reason that turbos and kids don't mix.
Something similar hapened to me many years ago in the wet. Damage was done and a lesson was learned, and it took me many years to shake off my issues with driving in the rain.
I'm glad you've learned your lesson. As Strutto said, go up to mount cotton and do some driver training as it's well worth it. also being able to "cut sick" in a controlled environment should give you some much needed experience so you can identify when your car has lost traction. if the revs and the engine noise don't match what your ass is feeling through the seat then back off. Where a lot of people run into trouble (and I know i did in the past) is when you put your foot down and the wheels start spinning unbeknowns to you and your brain thinks the car isn't responding, so you put your foot into it more. Tail end comes out then you freak out, slam your foot on the brakes (locking them) and wind the steering wheel to full lock. Once you do this you're pretty much screwed and all you can really do is hold on and pray.
Either that or boost it before the apex of a corner in the wet. It's just way too easy to do yourself permanent damage in a turbo in the wet, especially on skinny tyres.
