Great...if you are feeling lonely and self doubt, you have already hit the bottom..there is only one way to go now. up and above. This is where you need to start tweaking your business and revenue models. May be the customers are telling you things you are not listening. Take a deep breath and start doing small things. Conserve cash and don't do large campaigns. Test the changed model in captive small customer groups till it works. God willing and you properly listening to your market, things will happen soon. The best people to keep you company are your customers, when feeling lonely.
