COBRA quote is huge, any alternatives? - 12 months and counting

I was offered COBRA and the monthly cost is more than I expected as a marketing coordinator. It has been weighing on me all week. My old employer will not help with the premium. 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.
