Is it possible to get by relatively stress-free in the long-term with just a part-time job?

I know it probably depends on how many hours and how well it pays, but how difficult do you think it would be to make this work? Ideally I'd have a few roommates to split rent with. Also would I be without health insurance? It seems like most part-time jobs don't offer any. Sorry if these are stupid questions. I just recently entered the workforce, and I'm still trying to figure out how it works.
