Medical Testing and Expenses!!!

I am a 30 year old wife and mother. I recently started having severe seizures. I have been put on medical leave from work and have to see a neurologist and have many tests done. My family is really struggling now that we are down an income and we have now been told my insurance will not cover any of my specialist appointments or the tests I need done. I have to get these tests done to find the source of my seizures and figure out the best way to treat them. I am asking for prayers and any financial help anyone can help with. We have no idea how to pay for all these medical tests or even get our bills paid at this point. We greatly appreciate any help anyone can give. Thank you!!!
