I remember that feeling well back when I ran my own indie videogames studio. It could get stressful at times. One of the reasons I'm happier being back writing tabletop roleplaying games. Always enjoyed the game development and writing, didn't enjoy the business development and 'suit' stuff :D
Keep on going - it sounds like you are moving in the right direction, and for what it's worth I will be encouraging many of my friends to get the game as I think they will enjoy it.
