Vibrations in body. What should i do.

I am having this problem from last 2 years. I am having shaking all over body all the time. When they started I went to doctor and they diagnosed with essential tremors. But these are not stopping at all. I am feeling shaking inside and it is visible as well. Whereever I touch my body I could feel strong pulse including head. That strong pulse makes my head also vibrate. Even after using medicines for essential tremors it did not get resolve. 2 years back mri of head was normal. Sometimes I feel head rotating. Sometimes i feel vision blurred and heavy eyes. Ecg is also normal. Vitamin b12 is 150. I am taking injections from last 2 months but no improvement in symptoms. I have lots of anxiety. What should I do. Thanks in advance
