Hi,
Thank you for posting your query.
It seems to me that you may have 
valium (
diazepam) dependence, which may be aggravating the tremors. In any case, valium is not a good drug to suppress tremors.
Best options for reducing tremors would include beta blockers and 
clonazepam. At the same time, please meet a 
psychiatrist who would get you off valium.
Please get back if you require any additional information.
Best wishes,
