Niche panic attacks

I started my business in March offering a body therapy ( TRE ) to release stress and anxiety from the body working with the tremor mechanism.
My niche is: Women, who have panic attacks. More specifically women, who have panic attacks at work.
Now I’m thinking, my plan is to look for women, who have panic attacks at work and have tried everything else (talk therapy, medication) and I am offering this body based way to release the anxiety.

My question is, is my niche narrow enough?

Thanks a lot! 🙂
