Building new business/need to get over myself.

I have so many negative thoughts around my coaching business and fear of people judging me. I keep creating and taking steps every day despite feeling terrified. I do models on all of my negative thoughts around being seen and charging. I have my program created and am working on a more specific niche. I currently have 3 clients and have been making offers to people weekly. My niche is women who have 70 pounds to lose with food allergies. Is this specific enough and does this primal fear of coming out of the cave lessen?
