Niche help

I am having a difficult time coming up with a coaching niche and target market. I have years of training and volunteer work as a care counselor at my church and have helped so many people who have suffered with anxiety, depression and loss. I also sufffered with anxiety and loneliness for years and now I am thriving. I have a heart for lonely people and know how to help them, but I am guessing the demand would not be great. I also really know how to reduce anxiety and would love to help people through it. Im also torn on which market ro target. love working with college and young adult women and also women in their 50’s and 60’s. I realize the niche worksheet wants me to be a lot more narrow, but i would like to see most my clients in my home office. Im thinking if i am too narrow i wont get enough clients in my area. I really enjoy face to face interactions. What do you think?
