I'm sort of in a similar situation, but in the UK. The visa/work permit situation is a lot easier here though. So, soon after I started working on my startup I quit my job and got a new visa which allows me to do any kind of work (including self-employment). I also like it here and would like to stay until I get permanent residence. I saved up enough from my job to keep me going for a while, hopefully until my business takes off. I'm finding working alone on my startup quite hard. And all that emotional rollercoaster stuff I heard about also seems to be true. I'm doing it fulltime and still feel like I'm moving painfully slow. So I can totally understand your frustration and fear. I think I agree largely with what edw519 says. Keep the job and keep working on your startup but try and slowly build up the momentum. Is there a chance for you to get another less demanding job? It sounds like you must have a decent paying job, so presumably you can save a bit of money from that which could help. Finally, given your situation, the classic route of consulting might be a good option.
