COBRA costs more than my rent, what did you do? - 10 months and counting

I was offered COBRA and the monthly cost is more than I expected as a mechanic. Any experience at all would help. I saw that marketplace plans might cost less. Did anyone switch mid-year?

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.
