You sound desperate. Lol.

The best advice I can give is to decide ahead of time what fingering you want. Changing it each time will not help you, it will only make the practice more frustrating, and you will never get anywhere.

After this, practice the falling melodic lines individually, slowly at first, then at tempo. What I mean by this is: in these passage, ie mm 175-179, isolate the top part of the pattern (for instance, the Eb-Db-Cb-Bb-Ab-Gb-Eb-Db-Cb-Bb-Ab-Gb line in the right hand, excluding the eighth notes that are not a part of this line, but still WITH THE PROPER FINGERING). Memorize it. Then do the bottom line. Then do the same for the left hand top line. Then put the left hand bottom line. Then do the right hand and left hand top lines. Then the right hand and left hand bottom lines. All with proper fingering. This will help you get a sense of the shape at tempo.

Then, practice it blocked, moving from each position as though you were practicing a chordal passage, both hands (hold the chord, move as quickly as possible to the new position, but without actually playing the notes. Then repeat). After you can do this comfortably, play as written in three, four, or five-note chunks, hands alone first, then together, minimizing movement, but as fast as possible, laser-focusing in on the feeling associated with each change of position. Once again, do this with the same fingering that you practiced above. By this time, you will have started to glean a deep understanding of the passage that you will not get just from playing it slowly over and over again. Do not rush the final step of getting it up to tempo; you may need to repeat this process a few times to really get it down. Eventually, however, I promise it will help you move towards your goal of performance. This is a tough piece, best of luck!
