COBRA quote is huge, any alternatives? after 13 years as a bank teller

I was offered COBRA and the monthly cost is more than I expected as a bank teller. Any experience at all would help. My spouse has a chronic condition, so dropping coverage feels risky. Is the decision time really that tight?

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.
