maybe u locked the front end up and tried to turn? i've done this on my crosser at an estimataited 35mph(granted i was on a motocross track.. dont know how this really helps), bike slid from udner me... just jump back on it mate it can only give you experience
I think this is what I could have done tbh. In the moment of panic I think I tried to turn and hit the break at the same time to get better road position.
