Pressure testing my niche


Can I have your expert opinion if my niche is narrow enough, please?

Successful, over-responsible working mothers (30-55) that are superwomen (doing more than their share) that are on the verge of a meltdown or are suicidal that know they have to do a complete overhaul of their thinking and beliefs so they can get out of their own way to saying no and having an easier life.
