After consulting Google a few hundred times (with, obviously, no success), and then coming here and trying to decipher a few of the other answers, I've decided to finally just come forward and ask my question, and pray that someone can give me a nice little Christmas miracle to just make my day.
Alright, so, I have been turning some old .doc files into .pdf files in order to be able to read them in my new Kindle (it's the grey-scale one with wifi only... Uhhmm... As for 1, 2, 3, etc, I have NO IDEA... But I'm guessing it's a Kindle 2...? >_>). I finally mastered how to make the fonts big enough in the .doc file, so when I transfer it to .pdf and then over to my Kindle, I can actually read it without squinting or having to deal with the zoom in stuff.
However, I have run into a problem.
With some of these stories I have been putting onto my Kindle, there are some that are heavily accented with italics, whether it be to show the thought of a character, or to put emphasis on a certain (couple hundred) words. And, at times, the italics and normal fonts are used together to show a conversation between two types of characters... I'm pretty sure you catch my drift at this point.
Now, when I put these stories, these .doc transformed into .pdf files, onto my Kindle, I lose all that coding. It's all normal font. And it's not the .pdf file, because I made sure to skim through real fast and find my italics passages and saw that they transferred over just fine. It was the transferring from the computer over to the Kindle that had the problem.
I have tried things like putting my document into an HTML converter, so everything (such as the italics, page breaks, etc) had a carrot code (HTML with the little carrot signs). However, that did nothing, for when I transferred it over, it just showed me EXACTLY what I put in... As in, it showed me the carrot/HTML codes as if I'd just entered it into a word document.
I've been going at this for a couple of days now, and it really makes me quite sad that I can't get this to work out for me, because I'm one of those weird loner kids who'd rather sit in a corner and read a book than socialize with the other kids...

Though, in my defense, they're all pretty immature, even for seniors in high school. >___> But the point is is that I love to read, and I'd love to read (and re-read) these stories I'm attempting to transfer over so I don't have to be constantly glued to my computer (which is hard to do at school!).
Please, please, PLEASE... Can anyone offer me a solution? In plain, blunt English, please. I may be computer saavy, but when people start throwing big 'hacker' words into their explanation, I can get kind of lost. >____>
