need advice pls.maybe wrong forum..sorry

i have undergone a mri scan and eeg.this was because ive been having severe muscle spasms seizure like.these happen once a month to 2 weeks in a row and im in agony with my muscles constantly..well anyway they both came back clear and the neurologist decided that because i have depression its due to stress and as signed me off,but surely there must be other tests they can do before they write me off and just leave me dealing with this..it takes 20mg valium to stop these episodes.the doctor doesnt want to keep giving me valium so in a few days i will be left with no medication to stop these episodes,and without medication i get rushed into hospital to have it intravenously..what do i do to stop this without medication and can i ask for more tests to be done..pls someone give me some advice..im sure ive got some sort of dystonia but dont know who to see..thanks everyone
