Not sure how to narrow my niche


I want to coach people preferably overweight women who act needy and creepy in their relationships due to insecurities, feeling unworthy, self doubt and self loathing. I am looking at the Narrow Your Niche worksheet and I think my niche would fall under relationships but also health as in improving mental health with thought management??? With the submarket would it then be Overweight women as 1 defining word/s but I cant seem to narrow down the second defining words??

Would appreciate some advise here 🙂
