Re: If it wasn't for Hinata...
For a minor character...Hinata has had several moments that aided Naruto which is honestly a feat in its own (for a minor character)
First Exam for the Chunin Exams....Naruto is freaking out, and then Hinata offers to help him...he initially is sceptical...but she says this, "I don't want you to disappear here." It bolsters Naruto's confidence to not back down...he of course, cooly says he is simply too cool to cheat
Second, before Naruto vs Neji....Naruto is absolutely depressed and can think of nothing but defeat against Neji...Hinata tells him that she thinks he is strong because "he is a proud failure. Because even though he falls, he has the strength and courage to stand back up...and that is true strength" Once again it bolsters his resolve to fight.
Third, Last chapter. Naruto is crushed and broken, but through her words Hinata once again rekindles his Will of Fire to never back down.
There are 3 instances in which Hinata has picked Naruto up from the brink of despair....
Then you go and include the fact she has Saved him twice in canon situations: Indirectly against Pain. And a second time when she blows away the Mokuton spike about to hit him after he uses sage mode....It would have technically been three as she would've taken the spikes, but Neji saved her.
If you include the anime, then she also saved him against the Bee users in the Bikouchu arc, and she almost died saving him from the Magnet release user in the filler arc with the Princess acting as a merchant.
For a MINOR character...that is a pretty good track record of helping Naruto out...without her, things could be very different.
