Across the USA you should be eligible for COBRA. But that means you will be required to pay 100% of the premium for your plan going forward for a maximum of 18 months, instead of the typical 20% or less you may have been paying. They can kick you off the group plan after that.
So if you pay $400 a month from your paycheck for family coverage, you may find that the actual premium is $2000 a month!
In Oregon, the Democratic Party leftists (they can't run anything except a one-armed black lesbian theater company, and only so long as they don't have to break even financially) had a $300M boondoggle that resulted in no working healthcare exchange website and everything fell back to healthcare.gov as with some other States.
Losing insurance is a qualifying lifetime event so you can find your own insurance plan, often cheaper with greater choice of managing your own costs with respect to copay, coinsurance and out of pocket expenses.
Good luck.
