Going to court for a suspended license (florida). what should I bring?

I got pulled over a few weeks ago for my tags being expired and when I gave my drivers license to the officer he told me that my license is suspended. I was unaware and he said it was due to "financial responsibility". I looked into it and it turns out I had been pulled over a couple months prior and got a ticket for no proof of insurance. I paid the ticket and thought that it was taken care of. Apparently, now you have to get an SR22 form from your car insurance and present it to the clerks office in order to get your license reinstated. Getting this form is very expensive and I cannot afford to get it now. My court date is tomorrow and I have not reinstated my drivers license. What is going to happen to me?
