It's evident that you care deeply about the topic, and it's an important issue. I've been close to someone who was seriously affected by it, actually.

However, you're on the wrong course. You have a contribution to make here, but writing and marketing a guidebook or blog isn't it. Maybe you should focus on in-person counseling in order to help people. As your network grows, that might evolve into bigger events. My sense of things is that you can best get your message across when it's personalized and direct.
