if interest has faded and it is only you and no one else appears interested, then perhaps it is time to close down. This happened to me and I realized I no longer wanted to struggle and plan when no one else was interested and it was too much effort when only one showed up.
Refocus and organized so there is less stress on you. My group wnet from 12-15 down to one occasionally. When I sent out notice that I was discontinuing, no one begged to keep it going. One wrote me and said it was unfortunate but didn't say he would start attending.
