Any know of canon like stories were Harry's friendships with Ron, Hermione, Ginny, etc... fade, and he focus' on himself and doing what he wants as opposed to other people influencing him?

 

Well, that's the whole Independant!Harry genre, with few exceptions...

 

supposedly at least.

*self plug* You could try looking up mine! *grins* Eh...though please do read the warnings.

edit: Nope, never mind, you said canon woof. Not sure, but what you are asking seems contradictory, because I don't see canon Harry of any sort EVER just leaving Ron, Hermione and Ginny behind...EVER, unless they die somehow, of course.
