How Can Essential Tremor Disease Be Treated?

My father had essential tremor disease. I started having tremors in my hands and head 9 years ago and now they are getting worse. Hands and head shake, hard to get makeup on, hold eating utensils and hard to drink from glass or cup because I shake. I believe I have the same disease. I've seen many doctors, been told I had brain tumor, epilepsy, MS, possible Parkinson's. Testing showed no epilepsy, no tumor. I need a doctor who understands the essential tremor disease in Idaho. Can you help me?
