Treatment for Bella

Bella was diagnosed with epilepsy in June. Just last week, things changed and Bella became extremely sedated. Her doctors are unsure if this is due to medication or something more serious. She has been in the hospital with tiny improvements. The doctors want an MRI  to see what's happening. The money would be used for diagnostics and treatment. Bella is a rescue dog who was my husband's constant companion before his death last year and she has been my "grief counselor".  She has given so much to me and others that I want to give her the care that she needs but I am at a point where funds are very tight. Any help you can give for my sweet girl would be so appreciated.
