What would actually happen if I called CPS about my situation?

OK so I’m assuming pretty much everybody here knows why I would be calling CPS. A brief summary: I’m 13, I have asthma, and my parents don’t do modern medicine and I’m homeschooled so my mom is the school counselor. I’ve asked about 4–5 questions about different parts of my situation on here, and I’ve come to the conclusion that eventually someone (either from church, homeschool co-op, or I might even call them myself) is going to call CPS. What would happen? What normally happens, and what would the worst case scenario be?
