Insurances in Florida that will cover my mom's Trulicity?

My mother was diagnosed with diabetes yesterday, which has been hard enough on her but now her insurance is saying they can't cover her Trulicity prescription. The pens are extremely expensive, at 1000 Dollars a pen and our family can't afford that 4 times a month to start out like her doctor is recommending.

I've been trying to dig around and find health insurance in Florida that will cover her medication, but I'm 16 and don't know where to go or what to search for. Any insurance that's 100-200 dollars is fine, I will get a job to pay for it if we cannot budget that every month. But I just really need my mom to get her medicine, and I'm very worried about us not being able to find anything.

If anyone knows any health insurances in Florida that will cover it, please let me know. Thank you so much for reading.
