Look at ACA plan if you're laid off. Will be based on income, and you'd have no income. Likely a bit more complicated than that, but investigate it.
Generally if you want gov assistance in the US, you pretty much need to be poor for a full calendar year, plus about 4 months.
Also, in CA, you can make an "urgent" application and be enrolled within 2 days. I requires some pressing medical problem, but that doesn't have to be life or death.
It's really not. Also no asset test so you can have a nice house and $100,000 and you still qualify as if you were utterly broke.
