Stop working on it for a while, go get a job to sustain yourself, save up some money, working on it weeknights/weekends and once it's it at point where it reaches some sort of critical mass, quit the job and live off of what you saved up. It's like when you're playing starcraft, you don't have an adequate supply of minerals, and you keep unsuccessfully trying to harass the enemy. It's not going to do anything. You have to focus on getting some dough, ramping up your production and then punk the enemy.
