I need help fixing my extended essay question

Hi, I need help fixing my extended essay question. My topics are bio and psych and my question is "How does implicit racial bias in healthcare influence how often black people are diagnosed with Lyme disease?" My mentor said its hard to write about, so I need help fixing it. I've tried to restructure the question a few times, but I'm still confused, I wanted to make it about misdiagnosis and how black people are often misdiagnosed with diseases, but my mentor told me to focus on a specific disease, but I don't know which to focus on. She also wanted me to focus on symptoms of a disease that only black people get, but I've only found symptoms that black people have a higher chance of getting, and other races can still get those symptoms. Please help!!
