i know what you mean, it can definitely consume you if you let it. i kind of got to that point, it became my life, the only thing that mattered. i needed to step away for some perspective, i was also not focusing on my education or anything else really. that was one of the reasons we moved to the states. i was really upset at the time but it was probably for the best, my driving style has always been so ragged and on the limit that i probably would have gotten myself killed at some point if i had reached a higher level.
sad thing is i still think it would have been worth it.
