JosieDebbie,
I know nothing about endos in Florida but if you call your local (county) health department, they may be able to point you in a direction that could get you health coverage. Most (if not all) states have a plan for children with special health needs. I would try that. If that doesn’t work, you may try calling health insurance companies who may provide individual plans.
Best of luck to you! I have been where you are!
