Comitting to a memory system that works for you is always the hardest part, because there's no magical recipe that works for everyone. You need to really try different combinations and see which one you deal with the better, but it requires comittment and a few tries.
Since you already know a letter scheme and how to execute, you should try a different way to memorize things, because making sentences is not always the easiest thing to do.
Consider the following:
Instead of trying to build a phrase with the letters you come up with in pairs, think of objects or people that relate to you or that you can immediately identify with or know. The idea is to place those items in an order that will be familiar to you so you can automatically recall without thinking too much about it. One of the easiest ways to memorize things is to place them in locations you use every single day, like rooms in your house.
You can certainly know instantly what is where in your house, like your own room or the kitchen.
Close your eyes and visualize spots where objects can be placed or do things. Organize this list of places in a room in a clockwise manner, from left to right always, so you know where to begin and end. For instance, I can see in your room, there's a chair, then the bed, then the computer table, .... think of up to 7 places so you have just enough space to memorize like the edges if you have cycles. You need two rooms, one for edges and one for corners.
The advantage of using this method is you don't have to think what comes next in your room after the bed, you know by heart it's the computer without thinking at all.
The memorization process will then only be thinking of putting these objects/people/something that relates to you in those places doing something. The most important thing is those letter pairs can't be random, they have to mean something that says something special to you.
For instance, to start memorizing let's say the memorization you had before, you used the UJ OW IH DA NG
Let's pretend just for an example that after your computer you have your own box of cubes, a trashcan, a window, and a closet.
So to start memorizing, always going left to right, think of *your* Uncle John (UJ) sitting in that chair, farting or picking his nose and sticking it to the bottom of the arms, cursing at you and waving his arms around or doing something that is very familiar to you. Then move on to the bed and place there an OWl, with its big eyes, tearing appart a small animal and eating it, filling the sheets of your bed with blood and small bones. Then you move on where the Increadible Hulk, (IH) is sitting at your computer, smashing your keyboard and punching your monitor in a very angry mood. Then you can see your friend DAniel peeling all the stickers from your cubes and smashing your favorite against the wall. See him laughing evily as he's destroying your entire collection.
Then think of a big nigerian guy peeing into your trashcan, making all the stuff you have there kind of float around, smelling terrible.
It should be easier to go through the entire room you know by heart and reliving what's in each place. You can see these images more vividly and longer.
Do the same for another room you have in your house that you know very well, for the other set of pieces.
Remember that memory sticks better the more ugly, foul, sexual, disgusting and dirty it is and the closer to you the better. It's how our brains work and we should take advantage of that. Also, use your own language, no need to memorize in english. This was just an example, you need to make up your own things by yourself. It's your brain so it's only you that know what works better.
This of course was poorly written and not complete at all, and not the most optimized way to do it, but it should help think differently about memorization and improve success. You are not supposed to think while you are memorizing, you are supposed to feel the objects/persons/things that directly are close to you and say something to you and move on to the next location.
For further reference, see for instance Noah's channel on youtube, he has some good information about memorization.
Hope that helps out in some way. Having so many blind failures is very very sad.

But hey, I have had many almost successes. I have had quite a few successes with half solved scrambles. Meaning I solve the cube half way before I start continue the rest doing BLD. I think it will get better in time
