COBRA quote is huge, any alternatives? (Oklahoma City)

The COBRA quote for my family is $250 a month and I do not know how to afford it. This is my first time dealing with any of this. My spouse has a chronic condition, so dropping coverage feels risky.

I priced both side by side: total yearly cost, doctors in network and the deductible. Marketplace was cheaper for us, but only because our doctors were covered.

A quick call to the plan's member line cleared up two things for us that the letter did not.
