I have seen your replies, but first off, did you do an outline? If so, one thing you can do is make a more and more detailed outline. Once you have a detailed enough outline you have everything you want but you just need to write it out.
My advice is you have to have a story that you NEED to write. Also, people start a story prematurely. I take notes at least 2 years before starting a novel. You really have to think a long time before finding out what your story is about before writing it. Also, you can feel when you are ready to write it. I will be taking notes for years and finally it clicks and then I am ready to write it. On some level your brain is giving you ideas you do not actively think of. You need to figure out what your subconscious is trying to tell you and why you have ideas about this story.

Planning and organising make writing so much easier.
It is far easier to see the path through the woods from a balloon flying high than it is when you are down in the weeds amongst the trees.
And it is far easier to avoid dead ends and useless detours if you plan out the scenes before you start pouring out reams of verbiage.
First be creative with the plot and defining your characters then be creative with the actual description of each scene that the story needs.
Planning won't kill creativity. That is just an excuse people use to procrastinate because planning is hard work. But that work up front saves at least 10x as much work that would be needed if you just started writing and hoped to somehow magically come up with a great plot, interesting characters, and have the subplots and all the clues planted earlier come together at the end for a satisfying finish.
