Here is your problem.
Some founders milk company directly on bonuses and pay, there is no "grand exit" when they go public. I think you may be subconsciously aware of that, maybe there is some hidden regret or self-hate etc... Continuing with this frugality may not be way forward.
I would suggest:
- get out of NY, some nice environment near sea or forest, work remotely
- prepare for your exit. Move out of NY to minimize income tax etc..
- can you actually become CEO? If not, it is not your business anymore, not your problem
- find way to increase your take-home money. For start you could pay yourself for overtimes. Maybe if you move out of NY, you may need office there and so on...
- personal brand is worth quite a lot. Maybe there is way to use this startup to build your own.
