I'm facing an extremely difficult situation, so I am looking for your advice.
For the past 3-4 years, I have developed one product.
It's called Note Garden, in which users can take notes and keep them in memory by using algorithms. (Remnot has a similar concept.)
There is a very bad situation with this product right now. There have been many things I've tried, but there are very few users, and I can't figure out how to get them.
It is more serious when it comes to the team. I am near my limit of living expenses (rent and food). Both of the other members of the team have fallen into a state of indefinite dormancy, completely demoralized.
In this situation, how should I proceed?
It sounds to me like you've almost given up. :(
I don't know how old are you, but look... sometimes you need to get away from a project and its problems. Maybe it's days, weeks, months, even years.
Maybe the market isn't ready for the product as it now is. Maybe something pops up as an idea in the next few months. Find a job, get happy for a while. When you're ready keep spreading the word about the product and asking questions about it with your peers.
Everybody is going to have opinions. Listen to them all, negative and positive, and try to get some objectivity around it.
