If you think the startup is failing it is either because a.) the startup is actually failing or b.)you don't believe it can be a success and assume it is failing. Either way it doesn't sound like you are passionate enough about this startup anymore.

So the real question should be. Should you continue to work at a startup you have no passion for? The Answer is NO. Change jobs.

I am confused if other startups too would have these issues(Feeling of financial insecurity ,Lack of talent to mentor me).

I also feel ,if I work hard , build a strong technical team - the company then may prosper.But again,as you said,it comes to the same question - Am I passionate enough about the company to work hard and possibly risk my entire career(without working under a mentor).
