Please help Willow

This is Willow he is a 5 month old Ragdoll that suddenly fell ill overnight we do not know what is happening. We rescued him from someone giving him away because they were allergic. Our whole family jumped in the car on Sunday Feb 4th to make the 4 hour drive to pick him up. Every thing was perfect he is absolutely perfect and was the missing piece to our family for a short 2 days. Suddenly on the morning of February 7th Willow ended up having seizure like symptoms we rushed him to the Vet and were told he has an ear infection that is causing idiopathic vestibular disease we were prescribed medication and sent home. It is day 2 of him on medication and he barely has a heart beat. Mommy rushed him to the vet again and are doing a full blood panel, radiograph and every test possible to let us know what’s going on with our perfect boy. The vet thinks it might be a neurological problem and has suggested an MRI and hospitalization to monitor him. We are willing to do whatever it takes to help him but the bills in just a short time have come up to over 3k. We are begging for help to save our boy please help us out or share our story. Much love from our family to you.
