#block writer

Does anyone know how to get rid of writer's block?

I have the idea, I know how it should go, but I can't compose the narrative and this is discouraging me a lot. The amazing thing is that it always happens in chapter six. I have two stories stopped in chapter 6 (actually there would be three, but the other one I finished and posted the chapter, I just got discouraged from doing the seven)

Worst of all, I do not know if this is due to a block or if it is because few people read what I write (this in itself is already very discouraging, but I usually get around it).

I've done some research, but everything that I suggest I already do and now nothing works.

Conclusion: I am frustrated.
