You're going to get a ton of answers, from 'learn by ear' to 'go to Berklee', lol.
Since your thread title is asking a specific question addressing "You/Me." I'll answer with how I learned.
I picked up the guitar, liked it, and didn't really put it down for the first 2 years. I spent hours everyday sitting on the floor in front of the tape player hitting pause>rewind>play over and over.
I figured out Metallica songs are always riffing on that low E string, so I started using those songs to tune my low E string to. Most especially "the four horsemen" was used a lot. I learned the relative tuning trick (5th fret on E is A, 5th fret on A is D, and so on.) And I just kept at it. I was determined to be able to play the metal and rock songs I liked, and I was determined to be able to do it yesterday. So I had this mad fire burning in my ass to get better faster, as fast as I possibly could. Like there was something breathing down my neck going, "no, play faster! push harder! keep going! you're running out of time!"
after about 6 months I picked up Guitar For The Practicing Musician. A truly great magazine that sadly is no longer published.
In this magazine a brilliant gentleman named Andy Aledort had come up with this system (seemingly) called Tablature. And also within that magazine was a "key" to reading tablature, that showed all the symbols used, BUT not only that, it's basically also a page of tricks and techniques that you've got to learn. So I had this awesome page full of info (remember this pre-internet) and it was like finding gold. I memorized that page that night, and then spent the entire night going through the songs in the magazine, actually "reading" the music! I was so psyched. I watched the sun come up that morning and had successfully finished playing every lick of music in that magazine. I was stunned. Suddenly the knowledge of the page was the most important thing to me.
I did everything after that moment to get my hands on as much tablature as possible. Including stealing music books and magazines from stores. (hey, I was like 10 or 11 and broke, not that it's an excuse, but....)
I even raided my Fathers ammo bunker for "stuff" to sell at school.
I got arrested for that when I was 12. Turned out 2 Iron Maiden tablature books were not worth the wrath of my Father as well as the Montgomery County Police Department as well as the Fire Marshall.
By this point I had a small stack of books and magazines, probably a couple feet high. And I would sit there and play through the entire stack every day from first to last.
Then I wanted to read 'actual' music and not just tablature.
Again, I broke into the high school and stole the three Berklee Teaching Method books 1,2,3 from the music room, went home and started memorizing.
I learned to read music that night using those books. And they came in handy later as well, but that first night was the big one.
When I was 13-14 I joined my first Thrash Metal band with a bunch of guys who were 10 years older then me. They wanted me because I was a fast little f**ker on leads, and I had limitless energy at the time. I wanted to hang with them because they were 'A Band' and they were older guys.
Through them I learned about drugs, alcohol, and college girls. I also learned about ensemble playing and rhythm. My rhythm was terrible when I joined. The drummer rectified this issue by throwing drum stricks at me if I f**ked up. It only takes getting hit a couple times before you learn not to f**k up. After that I learned about grooves. How they can be pushed, or how you can lay back deep in them and make them push you!
Did that for a couple years, then discovered all new music. Tool, Soundgarden, Alice in Chains, etc. And I just quit playing for about a year. I didn't feel inspired to play so I didn't. After about a year of partying and having fun I decided I wanted to learn to play and sing all the Alice in Chains songs I liked. So I did that.
I started a few new bands. Some did pretty well, some not so well, some were fun, others not so fun, but I learned all along the way. And was still discovering new music that I liked, (like blues and classic rock.)
Fast forward a few years and I'd been homeless for awhile and found myself in Chicago. In Chicago I heard a style of music I'd never heard before called Flamenco. It was violent and passionate. Full of love and fury. I was hooked. More then hooked, I was obsessed with it.
Bought a nylon string acoustic and put my pick down, grew my nails out and didn't touch the electric for 2 years.
Then when I came back to electric I realized all that improv and fury, flourishes and passion that I'd learned through Flamenco, could be applied right back to the electric.
The only draw back was that when you play Flamenco on electric, people automatically label it as metal and shred music. (Which still makes me laugh.)
So now I play and gig around Chicago and am always looking to jam with people, pretty much in any musical style because I really like them all.
I realized lately I never thought about being famous with music, it's just a love and passion for the guitar itself that keeps driving me to play it and keep learning. I still feel like I barely know anything about the instrument and that just around the corner is the next big leap in my playing. Guitar can be addicting. I do wish I'd applied more effort to promotions and stuff when I was younger instead of always having my head down playing guitar, but such is life. Hindsight is always 20/20 right?
So in a nutshell, I just wanted it so badly, more then anything else in the world, to be able to make the guitar replicate the sounds I hear in my head. So I put my nose to the grindstone and never gave up, never let anything stop me, and just kept playing and playing all day every day.
It was almost like a rebellion. Rebellion is not giving up when people want you to give up, or when your hands hurt, or when your girlfriend makes your life miserable and b*tches at you that you have to quit the band and be "normal."
Just keep playing and learning, playing and learning, playing and learning.
Do your own thing, enjoy yourself, and don't listen to the haters.
Because there WILL be haters. (take it as a compliment, ... I do.)
Basically? You just have to want it. No one can practice or learn for you, you have to do it for yourself. I see this all the time in my students. The ones that get "good", are the ones that have that fire burning in them. They push themselves, they don't need to be told to practice or do their homework.

Now, all that being said?
If I were young today (early teens) I'd rather have a music teacher and the internet, lol. But it was different times when I was a kid. And even then there was no way I could afford a music teacher.
But a teacher could help you not form bad habits and can kind of guide you in the direction you want to go.
Best of luck mate, hang in there and just keep doing it. Some days are good days, some days are bad days. That's never going to change, so you just keep pushing forward.
I know this is a long assed post. But you asked a specific question and I figured I'd give you a specific answer. You asked, "what method did you learn with?" I call my method Shaolin Guitar.

I look at the guitar like Kung Fu. But that's another long topic.
Cheers!
