On viewing this a second time, I really must tell you what I see.
This piece is simply too difficult for you, and I believe its doing you more harm than good.
I don't say it to be unkind, but quite the contrary, to attempt to influence you to find something more in line with your abilities/development with which you can build forward instead of struggling.
I see you having a good deal of trouble playing both hands together, in time, and evenly, regardless of the passage.
Your finger work, also, is not precise or focused. To acquire the kind of technique to play this piece, one must imagine a very small spot on each key where you pull the key down with the smallest movement possible, consistently and with ease. This takes a good deal of training, especially with both hands in complicated passage work.
If you can do it musically, and slowly, the first few Book 1 Hanon exercises would teach you to place your fingers on the keys, and pull them down gently in unison, making each repeated motif a little musical expression. Also, this would teach you the gentle, very slight, rocking/rotation of the hand as it shapes itself to the keys. (Chopin taught that the 5 keys E, F#,G#, A#, B are the most natural keyboard shape for the hand). Oh, and if you do this, DO NOT pay attention to the instructions on how to practice the Hanon... its completely wrong!
Once you can do this, I'd move on to something a bit more challenging like the Bach Two Part Inventions, which Bach wrote as separate little studies to help his students with the greater difficulties encountered in his other works.
And basic scales are excellent also, as well as arpeggios, and such, played at a comfortable speed which is musical, as you control the keys feeling the weight of the keys as you pull each one down with a separate motion.
As I see it, these are the least of what you'll need to become fairly accomplished at in order to start learning this Chopin Etude, which would likely still be a formidable challenge for you, but at least by that time you'd have a reasonable chance of progressing with it.
Make no mistake... this is probably, IMHO, the absolute hardest of all the Chopin Etudes which fully exploits both hands. (most of them generally exploit difficulties in one hand, usually the right).
Its nickname is "The Torrent", and for good reason!<g>
I hope I haven't hurt your feelings, because this is not my intent, since I think being honest is the kindest thing to do.
Though admirable, I think you are shooting too high at this time, and need a good deal more foundation built before you can construct higher and higher structures.
