Hi kaanguner,
Firstly, you said, "I desire to learn piano through any means to be honest". This is an awesome attitude. An open mind will take you far in life.
I am going to reveal publicly for the first time my personal secret to success in any endeavor one takes on upon himself.
These are the 3 main ingredients:
1. knowledge
2. concentration
3. attitude
That's it. But you must possess or develop/master all 3. Having only 1 or 2 of them will limit your potential. Developing these are your responsibility.
Secondly, a teacher is an important tool to have in your toolbox which can "hopefully" aid you in the above recipe for success. However, a teacher should be far from the only tool in that box.
Thirdly, I gathered from this and your other posts that you don't have a teacher and can't afford one. Let me correct you there. You ARE the teacher and only one of the many you actually do have. You have a library card? Obviously, you have access to a computer. You have many, many teachers for free online.
Fourthly, I'm mentally unstable. So what. Have you ever heard of David Helfgott? Geoffrey Rush plays him in the movie "Shine" which is about a pianist that has a break down. Seriously, don't sweat it.
Fifthly, I too don't know where I want to go and for sure Chopin is a must also.
I am going to suggest using your computer and googling IMSLP. Search for Czerny Op. 599 practical method for beginners. Use the Busoni edition. Fingerings are provided for both hands. You will learn the notes and their time values and more importantly get fewer bad habits.
This entire method is available to watch on Youtube by many different performers so you can watch the hand movements and hear how they sound. This won't cost more than printer paper and some ink. Although it's cheaper to just buy it for a few dollars, easier to read, it's organized and you won't have papers all over the place.
Granted the pieces aren't the greatest sounding but are an incredible value. Whole notes, half notes, eighth notes, triplets, sixteenths, rests, ornaments, scales, chords, arpeggios, double notes are all introduced. Your open minded attitude and willingness to learn by any means will allow you to use this method.
I would also recommend Czerny Op. 823 if you can find it online or Beyer Op. 101 with Ruthardt the editor.
A teacher can cost thousands of dollars a year which is prohibitive for many. However, twenty dollars can buy a few great method books. I personally like and recommend Bastien and RCM.
Bastien is well coordinated and RCM will expose you to different periods, composers and styles. Bastien costs a few dollars per book and RCM just a few dollars more at the lower levels. These are copyrighted and you won't find them easily online. Then there is your local library. If they don't have them you can request they buy them for you! I do this all the time.
I strongly recommend against playing Chopin by ear or by rote. You must learn to read. Can you imagine not being able to read or write English? Well that is exactly where you are musically so start today, at once, do not delay! This is what I propose for you now.
Enjoy your journey, Joe.
