Have you tried the Patreon model? Ebook or courseware might work if you have loads of original content, but Patreon could be appropriate if you're figuring things out and sharing personal research and practices.
I do have a Patreon, but people who actually have CF have no money to spare as it is both debilitating and incredibly expensive (see http://micheleincalifornia.blogspot.com/2017/05/the-wrong-me...). Other people often tell me this is not pertinent to their lives. I think it has broader applications, but it has been really hard to try to figure out how to convince people of that.
