You just described the ideal use case for LaTeX! For really long documents it's especially good, because you can compile your chapters/sections/etc individually, if you set it up correctly. That way you only work with small documents most of the time, and don't kill your memory. Of course, LaTeX is a markup language, so you'll have to learn a new language to use it, but if you can get over that learning curve it is so worth it.
