Very lucky not to hit the wall at that speed. It seems to me that you got on the power too soon and too hard. That corner is very tricky and things can get very hairy if not done right.
You had planty of run of area and instead of trying to save it and stay on the track, you should have gone straigt to the grass.
I almost ran out of the road in that same spot first time, when i was learning the track. Twice, two cars spun right in front of me and i was able to avoid the contact both times.
Anyway, glad you didnt damage the car or yourself.
