I don't quite know how to word this, but let me start by saying I am
extremely frustrated at the moment.
Lately I have been suffering from long periods of "blockage", both mental and physical it seems, where every time I attempt to play the piano, all of my "technique" (it's debatable whether I have any) just goes flying out the window.
I mess up technically, musically fails to come through, I mess up phrasing, pedaling etc - Before long, I end up frustrated and stressed, kick the piano and myself and walk away cursing.
I am 17. I first started getting interested in piano around the age of 13, but could only afford a crappy electric keyboard to play on, until last Christmas when I bought myself a full size digital (Casio CDP100). Decent model, but lately I'm getting pissed off with it's sound and touch quality.
I've only had 1 teacher for a while in secondary school, but I don't want one now because they confuse me, pressure me and I play terribly around them. Plus I just can't afford one. I can read music a little, but no where near enough to sight read. I learn by ear and Synthesia to read the notes (cheating I know, a music teacher wouldn't be impressed)
As you can see, I've had a pretty erratic learning process, and now I am starting to think whether I have learnt completely the wrong way, and it can't be undone.

I don't see why, but I seem to have lost my touch. I don't wish to be a professional concert pianist or anything, but it is just SO frustrating when I spend many hours of the day listening to classical music, and I have so much music bottled up inside me and I can't get it out the way I want it to...
What AM I doing wrong exactly? I used to think I had a talent for piano, but now I think otherwise. I'm never satisfied with ANYTHING I play anymore.

Is there anything I can do to get past this? Is it normal for learners to go through this? If so, what can I do about it?
I think I better give you some examples of my piano playing, so you can judge for yourself:
(Fur Elise)
Sorry they are so cliche, I know people on here always go on about Rachmaninoff and the likes, but I'm no child prodigy, so...
I'm learning Clair De Lune at the moment. Or rather, I were - I can't seem to make the theme sing anymore, it comes out sounding very flat...

Please can anybody out there help me? Thank you for reading this mess
