Insurance Broker for a better price?

So, my insurance is going up from $76/mo to $520 which means I can't afford to have insurance.

A family member suggested I find a broker in my state (Utah) because they might be able to get me a lower cost plan.

I'm already bare bones. Bronze plan. $8000 deductible. $60 PCP copay. $90 for my endocrinologist. Right now my insurance covers 100% of my weekly telehealth psychiatrist appointments. I love my therapist and don't want to give her up.

So, does anyone have experience with an insurance broker, or have any other ideas? I don't qualify for Medicaid, and I'm self-employed.

Thank you!
